That's a bit of a strange question.

The 25 is a much smaller plane with no provisions or space for retracts... it is suited to electrification and I fly mine with two 3800mAh 11v batteries in parallel for 22v @ approximately 900 watts. It can also be flown with a glow engine and a fuel tank is provided.

The Bobcat 50 is almost twice as big, and can accept retracts. Some guys put Turbines on it too after modifying the fuse.

I also have a Falcon 1.20 which is again almost twice as big as the Bobcat .50. It features flaps as well.

All are different planes, so the question is sorta like asking "do you recommend oranges or grapes?".
