I like the Blazer brass just fine IME. My ranking high to low for 9-mm among the following group is:
Geco 115 and 124 (this is high quality ammo, IME)
Speer Lawman 115 and 124 (very similar to Blazer Brass except it uses a different powder based upon specs a couple years ago*)
Blazer Brass 115 and 124 and Perfecta are tied, and just slightly below Lawman in my preference, but I might not be able to tell the difference in a blind test (Perfecta is made by Fiocchi and is good ammo in my experience of shooting a few hundred rounds)
ZQ1 (I find no issues with this ammo)
S&B is last due to how dirty it shoots
I've never had a misfire or malfunction in any of my CZs or my Hi Power (or my 92SB in the years that I owned it) with any of the above ammo.
