Definitely shoot them both ... if the 1922 shoots better, then drop it into the 1929 wood and keep THAT one
... these are certainly rearsenaled rifles anyway, so I wouldn't think that there is any chance that the wood is original on either one. This way, you get the benefit of being the one who has the C&R.
As for next acquisitions, if you reload, the Nagant revolvers are a steal and are a nice match for your new rifle. Also, along those lines, don't overlook the TT-33's that are out there right now ... much nicer IMHO than the CZ-52's and are every bit as good.
