PST v. QA1 strut rods

I will be putting adjustable strut rods in my ‘68 notchback. Can’t figure out whether to go with PST or QA1. I’ve read just about everything I could find on this (and there is excellent, very helpful content here - thanks guys!) but I still keep going back and forth. Right now I am leaning toward PST primarily because it looks like I won’t have to take the whole suspension apart to put them in. Can I get some opinions on this? Is it true that PST can be installed without taking everything apart? Is that reason enough to to go with them? Is there a reason why QA1 would be preferable (other than price)? Thanks!

Good afternoon , I have a pair of PST arms with about 1500 miles on them . If your interested , $ 225 plus shipping from 34690. I will except PayPal.
Thank you
