hi doc, you gotta watch those punters!!! seriously though i have jamstix, and i have a Midjay+S90es combo..and for playing live, the midjay wins easily, simply for ease of use and variety of functions..but its also a lot more expensive (hardware-v-software)...i tend to use jamstix (as i will use jambass) more in the studio when writing stuff, ...if you were using it at a gig and you had an axeman and a heavy axeman you could do some damage i reckon...anyway hope that helps
