In the US, the two most popular deer rifles are the Winchester 94 and the Marlin 336, both in caliber 30-30. However, "best" is a matter of choice, and the area where you hunt. A bolt action rifle in a caliber legal for your state may be a good choice, and less expensive than the lever guns. I hunt with a muzzle loading rifle, and get to hunt 2 more weeks than the folks with modern rifles.
.243 or a 25-06
A 25-06... That's just me
That will depend on the individual. Some will prefer a shotgun and others a rifle.
.223 (maybe) definitely a .243. The BEST deer rifle is a 25-06 (Long story short .223 = good not much effect, .243 = GREAT for beginner, later on you will want a 25-06. 2-06 = BEST!)
