Being a shrimp-a-holic, that is an extremely tough question.
My top three in alphabetical order:
Caridina cf. Propinqua (Sunkist)
Caridina Serratirostris (Ninja)
Caridina sp. 'Dark Green' (well...Dark Green)
My fantasy/one day maybe i'll have species: Black Tiger
Of these, I keep all but the Ninja's currently. Until warmer weather sets in and they can ship again.
Of what I do currently keep, the hardiest by far have been the Blue Pearls.
Most active has to be a tie between the CRS/CBS and Tigers.
Most shy: Amano's
