I don't know very much about either of these brands, but if I were you I would stick to one of the larger, more well known names as they have been tried and true and most of the time that is the reason they have the reputations they have.... Companies such as JE, Wiseco/Endyn, Arias, SRP, and CP have pretty good reputations to live up to and are constantly reviewing their products and developing new ones to stay on the cutting edge and uphold those reputations.... in my opinion these brands are tried and true, and deserve their reputations... I would trust one of these brands over somethin I had never heard of anyday..... just my $.02
