They all have pretty different "feels", I would go with the one you like the vibe of the most. Suhr Moderns are a middle ground forward take on traditional specs, the Capa and Mayo are more typical thin neck/flat radius/etc. Also from a value perspective (as a US buyer) Caparisons these days are pretty close to the boutique US brands like Suhr and Tom Anderson, which along with my preference for more delicate feel would lead me back to Suhr/TA personally if I could only pick one, but its just a preference. All 3 seem to make exceptional stuff, and I drool over Caparisons all the time.
