I've not done any major replumbing yet but I've been watching Matt Risinger [1] on YouTube for a few months and have quickly become a PEX fanboi. He's a home builder based in Texas and uses PEX for basically every job. There are some videos on his channel comparing different types of PEX and PEX against other systems.
His channel is great but it gives a false sense of what can be accomplished on my budget most of the time. It's always far above what I can afford but If I can even replicate 10% of what he does I'll be better off than most.
