Newbie here - PEX-A vs PEX-B for whole house repipe, which one's better?

Alright, I'm a second year apprentice just starting to run jobs on my own, and I've got this whole house repipe coming up in south Florida where everything rusts like crazy. Boss wants me to use PEX but I'm torn between PEX-A from Uponor and PEX-B from some cheaper brand at Home Depot - the expansion fitting on A seems slick but B's easier to crimp. Saw a thread on r/Plumbing last week with mixed answers, and someone in Plumbers United group swore by A for the flexibility in tight spots. Watched a Roger Wakefield video that broke down the differences, but still not sure if the extra cost is worth it for residential. Any tips from you vets on what to go with for a 2000 sq ft house? Don't want to screw this up and have leaks everywhere.

goddamn apprentices always overthinking this crap, just stick with what your boss says and bill the hours.

fuck these supply houses pushing A like it's the second coming, B works 90% of the time and saves you 20% on materials. inspectors in my area don't even check the type.

go PEX-A if you're in a humid spot, expansion joints handle the swelling better without cracking.

we're all in this boat with cheap HOAs demanding repipes every 5 years, feels like a racket.

same here man, my first repipe was a nightmare with B kinks everywhere.

for south florida, definitely PEX-A - the UV resistance is no joke down there.

those damn big box stores selling subpar PEX-B, it's why we get all the redo jobs.

try the Milwaukee crimper with PEX-B, it's foolproof and under $200.

i feel you, stuck on my first solo repipe too and boss breathing down my neck.

Uponor A all day, the ring doesn't expand like B does in heat.

r/Plumbing had a good post on this, most said A for anything over 100ft runs.

grab the Ridgid kit for crimping B, saved my ass on a tight basement job.

PEX-B is fine for most residential, don't listen to the A fanboys.

watched that same Wakefield vid, he does A demos but admits B's cheaper for flips.

sharbite fittings with PEX-B, no tools needed and it's code compliant.

got a call back on a B install last week, joints popped in the heat.

my apprentice did a whole house with B and charged $4500, client happy.

haha, remember my first PEX job? connected it backwards and flooded the kitchen.

controversial take: PEX-B with propress fittings, best of both worlds no expansion hassle.

you're gonna hate chasing leaks in florida humidity, go A and sleep easy.

bro, i commiserate - my knees are shot from crawling under houses like that.

proud of my last repipe, used A and upsold a softener for extra $2k.

PEX-A is overrated, B with good crimps lasts 50 years easy.

fight me, but sharkbites are garbage for anything permanent.

use Viega for either, their pureflow system's bulletproof on repipes.

lol, south florida rust? try installing in the rain, that's real fun.

for newbies, start with B - cheaper to learn on without bankrupting the company.

test pressure at 80psi after install, catches 90% of bad joints right away.
