i bought an XS7 when they first came out. it was my first centerfire rifle. mine was 7-08. nothing bad to say. i like it better than the savage axis or ruger american, and it shot really well. i didn't keep mine long but had nothing to do with the rifle, i just wanted something else.
the irony of that was my next rifle was a ruger M77 stainless synthetic, and it turned out to be the worst shooting rifle i have ever been in the presence of. the barrel heated up a little and it literally wouldn't stay on paper.... it was bad. it shot fine cold bore, but went to hell fast.
i lost money on that one, because i had to be honest to the potential buyer, and think i let it go under half price... he got it dialed in though, free floated the barrel and bedded it. the trigger on the XS7 was way better too.
a Tikka was next, and i kept that one for awhile
ended up gifting it to my sis in law, she still has it and has killed a pile of stuff with it.
nothing wrong with the XL/XS7, for the money they seem to be great. i don't have a ton of rifles, so the few i have i want to like and appreciate. i didn't get rid of the Marlin for any practical reasons, i just wanted a couple nicer rifles.... took me a few years to get there, and there is only 1 critter between then and now i wouldn't have killed with the XS7
