They should not even be mentioned in the same sentence. I understand the history of both motors very well. One was too good for the track and banned (VG). More recently there have been people pushing 900+whp on the factory bottom end (VG30DETT). The other didn't see very much official track duty(SR). Infact the only real benefit the SR has over the VG is lighter weight and less complexity (as well as less overall potential). When we see stock bottom ended SR's pushing 700-800 + whp (most pop around 450ish whp) then they can talk.
