I've run Primary Drive, Sunstar, JT, and PBI on the front.
Sunstar lasts the longest by a good margin.
Next comes JT and Primary Drive. Primary Drive is significantly cheaper but often goes out of stock right about the time I need to order
JT is good quality but not much cheaper than Sunstar so I only buy them if I can't find Primary Drive or Sunstar in stock in the size I want.
PBI is Soft, noticeably softer than the other 3. A 16T I'm running right now showed visible hooking after 6k miles. I doubt it'll last much over 10k miles. A 14T Sunstar I've been using with the same chain after 5k it still looks new. The 14T is my offroad sprocket so it sees much tougher conditions than the 16T I only use for pavement/gravel road riding.
