I'll vote for the 10/22, because I love to be able to change the gun into, well, whatever I want. It's a chameleon - you can make it into a hunter, a target rifle, tacticool blaster, or whatever your heart desires. And then you can change it back, anytime you want. Heck, you could have a bunch of different guns, all with just one action. I can change mine back from tacticool to my fancy wood stock & Bushnell scope for hunting, if I so desire, in just a few minutes.
As far as the trigger goes, even guys who buy the CZ 452/455's, Weatherbys, etc. seem to want to buy parts to improve the trigger (there are lots of threads here to prove that), so the Ruger is no different in that respect. Probably some Remingtons have a better out-of-the-box trigger (although mine didn't), but many shooter choose to upgrade anyway.
Of course, stuff is availalbe for the 597 too, but the Ruger has literally hundreds of trigger groups, barrels, stocks, etc. that you can get for it, and most of them are very affordable. I like that.
Of course, in the end, it all depends what you want out of it...
