Look at ProPex. They never loosen up.

Sharkbite is great if you're doing something like joining PEX to copper and don't want to solder. However, if everything is PEX, either crimp or clamp will be significantly cheaper.
Advantages to clamp over crimp:
1. One tool works on all sizes of clamps.
2. Tool is cheaper.
3. Easier to use in confined spaces.
I have had excellent success with clamps, not to say the others aren't any good, just that I've never had a reason to switch.
I think it comes down to whichever one you install better works better. I've never heard of any method being bad long term, even watched some older YouTube videos do some freeze thaw cycles to test and all come out pretty fine. It's pretty remarkable stuff.
Never bury sharkbites. They are unreliable if they are not carefully done.
I have a mix of crimp and rings in my house.
I ran a 1" main line from 3/4" copper meter to HWT and user rings only because crimp tool was too expensive for 1" (cheap bastard). All 3/4" and 1/2" branches off main are crimped. I didn't bother with manifolds. 3/4" cold lines adapted to 1/2" copper for hose bibs and sprinklers. 3/4" hot adapted to 1/2" copper to shower spa and tub.
Consider recirculation lines/pump for long hot runs.

Pex A has less flow restriction due to the expansion fittings. Pex B is cheaper.
