"Is less gun sometimes more?"
Maybe,
Until recently I owned a very heavy rifle in .308w, it was better as an F/TR rifle than a stalking rifle, but it was incredibly accurate and was a great range toy or high seat rifle.
I also had a semi-custom 30-06 which was very muzzle-heavy and which could be a right pain to stalk with. A rucsac style sling was really the only way to carry the darn thing. Again, seriously accurate rifle and not ammo fussy, but heavy, long and very awkward to carry.
So
I got rid of them and got myself a Sako S20 in 6.5PRC to use as both a stalking rifle and occasional range rifle.
It's much lighter, dead easy to carry and so far has proven itself to be at least as accurate as either of the two rifles I got rid of, maybe even better AND has less muzzle flip than even the heavy 308!
I'll let you know in due course if it's any use on deer, but I'm not expecting any issues in that regard as others here seem to find 6.5PRC, with a decent bullet, to be anything but inadequate for UK deer.
So, maybe less will be more for me right enough - I certainly hope so
