A shutoff on PEX just seems too flexible to me...I prefer to transition to copper. If you do connect to PEX, a standard compression valve works just fine if you use the internal stiffener...the valves are identical. You can buy the stiffeners separately, or packaged with the valves. With a Sharkbite shutoff, you have the potential for it to turn on the tubing as well as flex the tubing. The SS grippers can gouge the PEX if the valve gets a little stiff when you're turning it. If you're not careful taking it off, when it comes time to replace it, you may have damaged the PEX, making a seal difficult or impossible without enough slack to cut it off so you have fresh tubing to attach to.
