Well, if I could only have one rifle, it would be a bolt action ... either a .308 or a .30-06. In fact (looks in safe), I only see one lever action in there, and it's a second-hand Marlin 1894 in .357 mag, "just for fun." Never hunted with it, and have no plans to.
But all I've told you is my preference, an opinion worth exactly what you paid for it.
