What do you think would be a good collection of rifles to hunt the world over and have the best rifle and caliber suitable for all the different species and sizes of game?

Also im not asking the best 2 or 3 all around rifles, what I am asking here for example is best beanfield rifle, woods rifles, mountain rifle, dangerous game rifle etc.
like best antelope/whitetail, then maybe caribou/elk size,
then like grizzly/moose buffalo/ elephant sheep/goats etc. etc.

just want to see what everyone thinks...
