Not really.
For the vast majority of shooters it won't make a difference.
My 1:12 Mini-14 stabilizes 60 grain bullets out to 200 yards just as well as my 1:9 M&P-15 and I don't shoot anything heavier.
As to durability, simple physics will tell you that the stress of imparting a faster rotation (i.e. smaller number in the twist ratio) is going to cause greater wear than imparting a slower rotation. This would be accelerated using bi-metal rather than gilding metal jacketed bullets, but, this will be meaningless to most owners since they will never use the rifle enough to shoot out the barrel.
