They are 2 entirely different guns. The 2022 and the 2009 are polymer framed guns. the 228/229 is an aluminum frame of the conventional sig design.
Like any Sig, the 2022/2009 are great shooters, and in the field of polymer pistols (glock, XD, M&P), they are a great value at the $500 mark! The grip on these Sigs is, however, a little bulky when compared to the 228/229, but if it fits your hand... then pick one up!
