Question Pros and Cons of PEX piping

I am going to replumb my house and am planning to use Vanguard PEX piping - existing pipe is galv, and I think tie ins will be easier. The pipe will be in a crawl space in coastal VA.

What are the pros and cons of this product?

If I go with PEX should I spend the $$ for a manifold?

If I go with PEX should I use crimp rings or do the side cinch rings work just as well - some of my connections will be in tight spots and the cinch rings seem more forgiving?

Any help or insight is greatly appreciated

Much easier to work/install than copper, but more easily damaged. Trying to retrofit and existing house with copper is no simple task, and often requires opening walls. The guys on This Old House love the stuff, and the manifold system makes runs with no joints, easy. Tooliing can be expensive, if trying to DIY.

I think there's mostly advantage to PEX, it's what I'd use.

Pex...

From a DIY aspect I was glad to try PEX, I added an additional outside faucet in my old house and it took me all day to cut, fit, solder everything together with copper. In my current house I did the same with Pex but it took me less than an hour with most of that time spent double checking to make sure I did it right because it seemed so easy.

I picked up a crimping tool that does 1/2" and 3/4" for ~$90 at a local store, could be cheaper online. I figured the $90 was less than I'd pay to have someone install it for me and now I have the tool in case any of the existing PEX has a problem.

Is velocity noise in Pex quieter than copper?
