Unless you were to get a lemon from any specific manufacturer, which is always possible, a Jewell, Trigger Tech or Timney will all not only suffice but will be a significant improvement. I don't think you would regret any of those. I have used all three and I guess I would say that I can't tell the difference. Maybe I'm not good enough or sensitive enough to tell the difference.
