I wouldn't say I have a favorite brand but now that I use them it's hard to live without them. Most of the name brands are very good. I have some moultree cams and I also have some cheap off brand models and they do just as good.

I've never had one, though I think it would be interesting/fun to use. I like all the pictures people show of what walks by... ;-)

Maybe some day... 

I had a moultree but it broke for some reason.  Right now I have a cuddeback and I like it better because it simple to use, long battery life (I dont know if the life is better than the moultree though) and I like the night pictures better.  There easier to see in my opinion.  But also there alot more money than moultree and a lot of others, and you could get by with the cheaper ones because they still do everything the other ones do.

I don't own one but have started reading about the different kinds. When I get one narrowed down I will let you know
