i like sony acid (i also have reason, so i know what you mean). its all about rewiring reason through a DAW like acid, etc. to get it to sound better. sorry i cant explain that to you though, as i have yet to try it myself. search for tips out there.
as Kama says quite right, get something to suit your needs and budget. Propellerhead are bringing out a seperate bit of software soon for these exact purposes called 'Record'

im sure there are more out there, but they essentially do a similar job - sequencing
