Get 20amp. They're not that much more. Other than that I'm not sure the break matters. I don't think I've read anything about any boutique breakers on these forums. I have read about boutique (read: cryo) in-wall wiring though.
Also get some Walker SST or the newer Extreme SST. Have your electrican paint the SST on all of the bare metal contacts. Just tell him it's "electrican's paste" albeit much higher quality.
