I use my 300wsm in a variety of terrains for Elk and Black Bear. Most of which are the heavy forests of Washington with clear cuts. I put a Leupold 2x-7x 32 on it and it has worked just fine for 3 seasons.
For deer and other critters I use other rifles.
A 270wsm with a 10x Bushnell Elite in the open prairies and desert.
A 30-06 with a Burris 3x-9x 40 as an all around hunter when the weather is wet and a short compact 30-06 with a 4x Leupold, when I'm hunting the thick dense undergrowth of the rain forests.
I like all three makes. They all have good clarity. I can't say that one is better than the other but, the Elite is a very nice scope.
If I was going to use the 300wsm in Montana. It would have a 3x-9x 40+ Elite on it.
