It depends on how you define rifle. The SMLE doesn't suck too badly. The K-98 is a fine, fine gun. The FN FAL is sweet, everybody should own a half dozen. The AK-47 has some good points and some very, VERY bad points. The M-16/AR-15 rifles are toys. Personally, if I had to pick just one rifle, I'd go "heavy"...and stick with the MG-34. It's select fire, it's in a decent caliber, and when properly tuned it runs like a scalded ape. It even has a nice handy bipod.
