Pex-A and Pex-B are both acceptable and will outlast any house you install them in. Pex-C and Pex-Al-Pex is not good and can fail if frozen or subjected to some installation methods.
Pex-A is not better tubing than Pex-B, the A-B letters simply indicate that the Pex-A process was invented before the Pex-B process. Pex-A is slightly more flexible than Pex-B, Pex-B is more uniform in wall thickness and will often outperform Pex-A in strength both in freezing and temperature performance.
