I would call Minitab the “Cadillac” of stats packages. It’s got the most robust set of tools and I personally like it’s graphics the best. That said, I use SigmaXL and QI-Macros more frequently because:

  1. I switched to a Mac and can no longer use Minitab
  2. Many of my clients have budget constraints and those two have lower price tags.

I’ve also used SPC XL which is good. If I were you I would download a trial package of each of them to see which one seems more intuitive to you and which one fits your budget. I hope that helps!
