I prefer regular brass but I still have a lot of .357 nickel brass left that a guy at the gun range gave me some years ago at the indoor range, mostly Win white box. Some of it's been loaded quite a few times. My experience has been mostly case mouth splits but it's lasted much better than what I've heard from others but then my range load of 7.4 grs of HS6 under a 158 LSWC bullet is pretty mild.
