Planetary imaging question... FL vs. Aperture

Hey... I've been looking around here and there and have seen some really well priced 2nd hand scopes available..

My question is this... all things being equal, does focal length win over aperture when planetary imaging?

Im currently using an 8" F/6 newt (1200mm FL), Would images be better out of a 6" F/10 Mak-Cas (1800mm FL) or would it just be larger, but lacking detail due to less light gathering power of the 6" vs the 8"
