   I like the idea of expanding the tubing since the tubing is trying to go back to its original state around the fitting.

   One other difference. The inside dia of the fitting is bigger for the expanding system.

   Not that it will make a difference.

   The cost is higher for the tool.

   I believe this subject came up within the last six months and as far as I can remember more people liked the expanding system vs the crimp type systems.

   After saying that I've used the crimp system and not had a leak yet.

   Remember that when using PEX, you need to use the 3/4" size to connect your tub spout to the mixing valve of the shower. The smaller internal diameter of the 1/2" or 3/8" fittings won't flow freely enough, and water will always pour out the shower head when you go to fill the tub.

   I would use the expander. I have never had an leak on any connections.

   Check with your local supply house as to what is available.

   I have the expander and crimpers. Moved to Utah & no fittings or PEX for my expander. Now I'm in New Mexico and same story, no local source for the Wirsbo brand PEX.

   You're either going to be buying over the net or using what you can get locally.

   When you only need a couple misc fittings you want to be able to get them now, not next week.

   Yes, I'd say that's correct. My plumber and I both used crimp-type. No problems at all.

   ...But I've heard plenty of good stuff about the Wirsbo-type expander method too.

   I'd go with local tool and help availablility dictates.
