As Jeff has mentioned, the resolution of both setups is quite similar (A=0.164 arcsec/px, B=0.147 arcsec/px).
If you wanted a setup that was more resilient to sub-optimal seeing then i'd consider configurations which give a more coarse resolution. eg setup A without the barlow (0.214 arcsec/px), and/or a camera with larger pixels eg ASI220 with setup A (with barlow) would give 0.227 arcsec/px, and with setup b (without barlow) would give 0.295 arcsec/px.
