Bf-109 G-10 worth unlocking?

[SeaCat]

I've gotten the K and not the G-10, and I only fly Bf-109's. I switch between the F-4 and the G-6, I don't really think I'll use the G-10 too much. I tried the K-4 once and it just couldn't contend with the spitfires and yaks on sim. However, I was trying to be the wingman of a Spitfire, so I couldn't properly get any Boom and Zoom action going. The K definitely has firepower, though.
