I own a G22. I do not recommend it.
I passed up a chance to buy a Buckmark Sporter at a good price, and sometimes regret this. I do not like the field-strip procedure for the Buckmark, which IIRC requires you to remove any scope you've mounted, but it looks cool and should be high quality.
So, between your two initial options, the Buckmark by far.
I would also seriously consider getting a 10/22 and customizing it, though. Good rifles, tons of aftermarket support. I would do that before getting any of the AR-styled .22s which mostly are overpriced and of dubious construction. If I wanted an AR-styled .22 I would get a real AR-15 and add a .22 upper or conversion kit.
