lol...ain't this place great eSheri?
Seriously, ultimately,
you are the

Objectively, the K3 is newer and is "the latest and greatest". But the K2 is absolutely no slouch it would appear and also has the significant benefit of maturity on the market. Differences in size and weight and keyboard layout/navigation and display should also be taken into account, but again, only you can be the best judge here.
I already threw my 2cents in
I repeat: Ain't MobileRead great?
