Jarrey,
"..........which has more great features than the other."
Only YOU can say "what is a great feature".
".........which is more reliable......"
If you are talking about bolt action rifles; you rack over a round and pull the trigger, it goes bang.
I own a X-Bolt Stainless Stalker (love it)............and I would buy a Remington 700 XCR anyday !
Depends on which features YOU want in YOUR rifle !!!
Not for nothin, but I not a big believer in short mags.
Never found a "need" for one.............
