9 Cropper 15 Cropper Oasis Bonuses Distance Whats most important?

Considering a village to make my third and I want an offensive army base where I plan to build my main army, in your opinion what is most important, distance to your capital, oasis bonus amount or # cropper? or combination. There is a 9c 75% oasis bonus 8 blocks away from me I'm thinking of and a 15c 100% oasis bonus 11 blocks away.
Thanks for your time!
