I've used both several times on tanks, and had no real problems with either. The spa flex really isn't all that flexible without heat forming it to what you want. I generally use some flex on external pump inlets/outlets to try to isolate any vibration, but other than that I use mostly PVC.

I will say you need to be a little careful about gluing up the flex then bending it etc right away to fit other fittings. Its needs to cure up a little before you move it around too much.

Talking reef website had a cool story about a PVC pipe bender that looked pretty slick, and could maybe be rented? I thought about looking into that next time.

Thanks I am having the problem getting it on the barb connectors. The other concern is removal if I need to.

It isn't made for barb connectors, but you could probably heat the end with a heat gun, or carefully with a torch. Slip it on the fitting and let it cool.

Carefully! Heating/burning PVC will make nasty fumes. Spa flex will probably also.

Spa flex is made to be glued into regular PVC fittings just like rigid PVC. If you want to use hose barbs, then use vinyl tubing. I've found spa flex to be pretty difficult to work with since it's not all that flexible, but heating it may help. Also, it requires a different kind of glue than rigid PVC (although people have used the regular glue without problem).

do you glue spa flex to connectors? Someone suggested using the SPa flex but I am not sure I am liking it.

Yes it is made to glue into regular slip PVC fittings.

Oatey makes an all purpose cement I use for both spa and pvc.
