My feeling is that as long as your still & not skylined (keep some broken cover behind you) & your color pattern somewhat matches the habitat you're in, the specific pattern or brand doesn't make much differnece.  It's kinda like asking which brand of rifle is the best.  We'll argue about it forever but in the end it boils down to personal preference.

Here in the west, I prefer the sage patterns but use Mossy Oak & Real Tree as well.  After 5 or 6 days of camping & hunting, the type of camo I choose is the type that's still clean.  The one piece of camo that I've used for just about every type of hunting (ducks to javelina to elk) in all types of cover (desert to dark timber) is a woven sweater in ASAT camo.  The broken but open pattern just seems to blend in regardless of light or background color.  Predator camo seems to have similar qualities.

Camo companies are constantly trying to attract customers from competing manufacturers & their product is always the "Best" there has ever been.  It won't surprise me when some company comes out with the ultimate pattern that amazingly looks just like the large plaid patterns Grandpa used so efficiently back in the day.

Where I hunt, I am pretty mugh sitting in or surrounded by Oaks.  Therefore, I use the Realtree HD Hardwoods, and it seems to be good enough.

It is all in what you want to spend your money on, and the manufactures will create a new pattern next year for you to buy. 

When I first started to archery hunt my cammo consisted of a flannel shirt and Levi's.  It has now progressed to military BDU's in woodland cammo.  I have never seen a need to use anything else.  The main thing is that you want it to break up the shape of your body into irregular lines, but then I have been within 5' of both deer and elk with a vest or sweat shirt in hunter orange on also. 

I do wear camo most any time I'm in the woods. When I have to wear blaze orange for big game hunting, I wear blaze camo where legal. As far as any pattern being superior to others, I'm a tad skeptical about that being so. Heck, I've even read where someone suggests in an article about camo, that a hunter "mix and match". I probably do prefer the patterns with a lot of greys in them along with my other favorite pattern, "outfitter camo". It's pretty plain and has very subtle contrast and seems to blend well in any number of areas. I don't wear the old BDU patterns any more, but I think I just got my fill of that in my former job. 

I'm only concerned with camo when waterfowl hunting.  For that , where I hunt, Advantage Wetlands, Advantage Timber, and an older Mossy Oak reed pattern works well for me. 

For most rifle biggame hunts anytime I'm required to wear blaze orange I'm not too concerned with wearing camo for camouflage.  As long as the weather isn't too wet or servere my basic elk, deer, and pronghorn outfit is a pair of Carhartt or Dickies canvas carpenter pants topped with a coyote brown colored polyprop zip-t under an Advantage Timber camo'd long sleeve crew neck t-shirt. Base layers of polar fleece or polyprop depending on the weather and temperature.

I think Coyote Brown as used by the USMC is probably the best of the solid colors that blends in with almost any terrain and vegitations.  Muti-cam also works well.  I like olive drab as long as it's not too green, preferably an OD that's more khaki colored.

Just make sure you wash all your hunting clothing with a detergent that does not caintain UV brighteners or enhancers.  Many commercial laundry detergents contain UV ehancers or brighteners to make colors look more vibrant in natural light. 

Because I've had other hunters wander on to my land, I wear blaze camo.  So far I've added a hat, vest and sweatshirt.  Deer don't see it (I had a muley buck within 20 yards and all I was doing was sitting still on teh ground), but you stand out like a lighthouse to other hunters.  It sure would be nice if more companies made a blaze camo jacket, but the only one I have found is in cabela's catalog and it is pretty pricey.

In my state you cannot legally wear blaze camo patters to fulfill the requirements for blaze orange.  It has to be solid for that requirement.  That's not to say that you can't wear it, you just need the solid vest and hat to go along with it.

I have never put much stock into these new wave camo patterns that are coming out every day.  I have hunted in woodland BDUs for years and the Indiana game doesnt seem to be bothered by it.  THAT BEING SAID.........Natgear snow camo and realtree AP are the only two commercial pattersn that I will use.  I used military snow cam or a white sheet for years.  When I got the natgear, I could not believe how well you disspaear.  My hunting bud uses natgear snow camo also, and when we set up for coyotes, if I dont keep my eye on him when he goes down wind to sit, I will loose him.  I also like the real tree AP.  As an outer jacket, bibs, or rain gear.  This pattern is definatley one that will not turn into a black blob at 200yds.  Other than that, I will always wear woodland camo BDUs.

One of the best I think so far is Multi-Cam.  It's not a pattern marketed to the hunting crowd.  More or less designed for the military type useage.  I will say that so far I haven't found too many patters that blend in to just about anywhere like Muticam does. Problem with a lot of other camo patters is that they are too dark with way too much green in them.   A lot of hunting patterns are too specific, designed for specific backgrounds and vegitations.  Even for waterfowl I haven't run across a camo pattern that really blends into dead tan colored cattails all that well.  Most patterns are way too dark.  I think both Multicam and digital destert camo is a better choice for dead cattails than shadow grass or advantage wetlands is. But as said before, for giggame rifle season I don't see any need for camo.  I sometimes wear a camo shirt just for utility purposes, but with 600 sq inch of solid blaze orange require, camo is a mute point here.
