In my opinion....
Lots of carts in that price range smoke the Grado cartridge. Denon 110, ATVM750SH and Soundsmith Otello are three that quickly come to mind in the price range of the two carts you are asking to compare. All three are high output (or high enough to work in MM inputs).
Can't pass judgement on the Rega, but suspect it is similar to other Rega underperformers. There are other high output MC carts that will better the performance of the Grado.
I had a Grado Sonata and gave it away to someone who makes his listening decisions based on magazine review more than his own ears. He was disappointed in the Sonata as well compared to other similarly-priced carts.
