Go with the PSA and save a few hundred. If you feel the need to modify later you can change anything you want on the upper!
Don't know that I would say that is a great chart. Stag is only going to put information on there that makes them seem to be the best. No sense in advertising someone else has a better this or that than you do. But, it's a good start. I believe Spikes has the same type of warranty structure as Stag and possibly DD as well.
