Ceramics can have a bit less bite when cold, but I think it's more-so the different initial bite most perceive as a decrease in bite. The OEM pads have a lot of initial bite whereas most ceramics have a more linear build up in bite. Once the ceramics get some heat into them, they seem to have even better bite than OEM (good quality ceramics that is).
Try looking up the friction ratings on the pads you do chose.
Akebono Euro Ceramics are a pad that I love and they will end all brake dust worries if you like having clean wheels. Everyone asks me how I keep my wheels so clean and are surprised when I tell them I can't recall the last time I washed them.
