I'd recommend a Charles Owen, they're cheaper then Samshield, think they're really classy and they fit my head perfectly so maybe try on one of those? I'd recommend just going into a tack store with an open mind and not worrying about what brand, just about the fit and how you feel in it.
I highly recommend KEP they are really good and safe but quite expensive
I love Troxel, but they are more on the cheap side, I REALLY love Ovation Helmets!💚
Samshield or kask are one of the safest ones!
