I've tried the Callaway, Ping and Taylormade, got a good pro at the Club that just lets me mess about with the new stock in the Sim

( Probably because he knows I like shiny things

)
Currently play the Stealth and love it, won't be changing it but we won't tell the Pro that.
Callaway I dint like it - obviously a personal thing but it didn't feel very nice off the face, didn't help that there wasn't a good shaft for me to test with
Stealth 2 - very similar to mine a bit more forgiving but not going to save my bad shot which is me not the club
Ping - hit this the best feels nice no longer than my stealth, but found this super ugly at address hate the turbulators with a passion
I'll be saving my money this year and getting some lessons instead
