What's the best kind of deoderant?

ok my armpits are really sensitive..i have to wait like 2 or 3 days in between shaving (i know that's gross) because they hurt so bad to put deoderant on....i have tried that sensitive skin stuff and it doesn't really do anything..i have tried powder but that shows...and while i am asking things...what is the best deoderant for no white marks...the clear stuff still leaves stuff and it doesn't seem to work anyways....and the invisible solid sh*t is such a crock!! my mom in law suggested the spray stuff but i have never tried it..does it work with those areas?? sorry this is such a long one but i have been wondering these things for a long time!!
