It probably depends on your own preferences more than the specific genre. I do very much like MC cartridges because they’re so detailed and lively. But I tend to prefer the warmer voiced MC cartridges like Koetsu, Benz, Shelter. I really enjoy these cartridges with some heavy metal, but some might prefer that music with a more tipped-up sound.
The 2M Blue is indeed slightly bright, especially compared to the 2M Red (which is vastly inferior to the Blue, overall) but it certainly doesn’t have the detail or drive of a good MC. The Ortofon Cadenza Red is kind of a good analogue for the 2M Blue in MCs - slightly lean, slightly tipped up, but great drive and detail that can be a lot of fun with rock & metal. Then the Cadenza Bronze model takes that and adds warmth, and fullness (at a higher cost) - even better IMO. That said, a good deal on an imported Benz (audiogon ads) is gonna be hard to beat for the money and I do really enjoy some heavy metal on them.
I’ve enjoyed stylus profiles from plain elliptical to extreme micro lines / micro ridges / etc so I wouldn’t get too hung up on that. What IS important is to get a nude stylus (which your 2M Blue already sports). And cantilever material will probably have a bigger impact on sound than the stylus profile.
Phono stage (or SUTs) is gonna become an even bigger deal with MCs.
