I think it’s better than the remchester domestic stuff. The primer pockets are the main difference in my experience. They don’t loosen up as fast and seem overall to keep better tolerances even when brand new.
But if you’re not seeing a difference in your shooting, then no, it’s not necessary.
I’m itching to try some of the high end domestics - Alpha and Peterson. I havent heard a bad report on those yet.
I just bought 100 cases of SIG 223R braass at Cabelas for $30. Went to ream the flash holes like always with first time loading and all were perfect. Primer pockets very tight after 8 loadings so far. Seem to give as good of groups as anything else I've tried. I'm impressed with this brass that is very inexpensive.
