At present I have two of each. They both make for an excellent utility rimfire longarm. How particular features of each model figure as pluses or minuses has to be a matter of personal opinion. The best way to figure it out for yourself is to see if you can't wrangle an opportunity to try one of each and see what suits you better. If you can't arrange to strike up an acquaintance with someone who owns them, you should be able to pick up a used example of a basic model of each in good shape for around $200 or less, total, easily.
IME, most of the feeding problems attributed to M-60s that I've seen were basically due to overlubrication. Blow-back operated rimfires are prone to depositing unburned particles of powder back into the action. If there's too much oil, grease or any other "wet" lubricant on the moving parts to catch and hold it, it turns to a sludge that'll start to inhibit proper functioning in short order. Switching to a dry-film lube, or at least cutting 'waay back on the oil, will cure this in almost every case.
FWIW, the vast majority of the instances where I've run into folks experiencing chronic feeding/function problems in
any brand of .22 semi-auto with no underlying mechanical issue could be traced to the same thing: Too much lube. Usually, they'll try to "fix" things by dumping more in it when things start to get sluggish, which just compounds the problem. I've been able to pick up some nice little rifles real cheap from folks who wouldn't believe me when I told them that
In terms of practical accuracy, when fed the brand of ammo the individual weapon seems to favor it's pretty much a toss-up, IMO. Either is generally capable of putting things into a smaller hole than most of us mere mortals can hold for when standing on our own hind legs, and even a bench and bags will tell you more about how well
you can shoot than what the "inherent" accuracy might be in most cases.
