Touring productions vary widely, from Broadway-like full productions that run for weeks in each city to minimized non-union productions that usually play for a few nights.
If you care a great deal about a show or want to see a particular performer, go to Broadway (since NYC isn't very far). But if you're seeing a show just out of curiosity, you will probably be fine with a first-class (i.e., union cast) tour.
I've only see one non-union tour (HAIRSPRAY) and, actually, it was pretty good. But I admit l'm leery of non-union shows where the major parts are adults. A non-union GYPSY came through town and the lead may have been wonderful, but I had to wonder why she didn't have a union card at the age of 50. So I skipped that.
(One possible answer is that LA-based actors don't always join the stage union because there isn't enough West Coast stage work to justify the cost and the inability to take non-union jobs.)
