I ordered this to have on-the-road where I prefer not to bring my trusty Sennheiser e835s. Compared to the Senn, the AKG sounds a little bit brighter, and has slightly different sound to my voice. But I don't feel I strain more or less when singing into the AKG. It sits well in the mix with other vocals, drums, guitar and keys. Tried it on two small PA systems and it sounds very good in both scenarios.
In other reviews I've read it's more quiet than other mics, but I didn't experience any lack of volume. For half the price of the Senn it sure hits the mark for me. If you need a good all-rounder vocal mic for a smaller price, this might be the one.
