Every situation is different. I use and like 50mm objectives on several of my rifles. But I have smaller objectives on others for very good reasons.
One cannot really generalize.

True .
Here in Florida we night hunt hogs and don't walk very far to most stands.
I was admiring my 4x12-50 leupold vx-r last night while hunting ,with a near full moon and very sandy [white] ground I could see the feeder area just fine with no light at 200 yards.
I also use 50's on a couple of Conquest's long range rifles ,not that a 40mm wouldn't work but the 50mm does give better night time resolution on higher power settings.
