The difference in calibers you mention is important.
What do you want out of the gun? Would it be a dedicated deer rifle? If so, then you should get the 30-30 and my suggestion would be the Marlin 336. Winchesters are good guns too, but prices on them are too inflated, bs in my opinion, and I personally think the Marlin isa better hunting gun as well. I have had a Marlin 30-30 that I shot, and won, in several Cowboy long range events, really liked the gun. Traded up for a Marlin 336 Cowboy in 38-55 and never looked back. Superb gun.
If you are looking for a gun you could deer hunt with, out to about 100 yards, and be able to shoot small game with reduced loads and plink for fun, then my suggestion would be the Marlin 1894 in 357. The 44 or 45 would be ok (probably a tad better for deer), but for plinking 44 and 45 ammo can become a bit expensive. If you reload, you can load up some very fun rounds that shoot around 650 fps in 357 all the way up to full magnum, jacketed rounds for deer. I shoot cowboy and have a 94 in 357. I have been shooting the gun for 6 years now and a very conservative estimate on rounds through the gun would be between200 and 300 thousand. Admittedly, I only shoot lead bullets at around 700fps but I have only had to replace the carrier in it once due to wear, but nothing else. These are great guns and will last forever.
Good luck
