Its not snobbery, Paul. Its bitter experience.
Bought my first PX bike 12 years ago. It had a design fault which meant anything larger than an 11t sprocket on the cassette wouldnt fit. (Not the last time PX fucked up a design. Anybody remember their top carbon frame that could only accept Campag? ) They got a drawing wrong.
So I sent it back. They replaced it with one from a new batch. I could fit a wheel in the back this time but the steel forks were so noodly that desceding was appalling. I bought some carbon canti forks from them that they said were compatible. But the bike just had a mind of its own. So I sent it back. They sent me a replacement that worked. 3rd time lucky.
Then I bought a track chainset for a track frame. I feitted it and the chainline was 10cm out (
) Turns out they'd cocked up the spacing and made them for 130mm spacing and not 120mm track standard.
Then I bough a pair of winter gloves. They work once. Because when you pull your fingers out the liner comes out with them and is impossible to put back. Etc etc etc.
Sometimes they get stuff right. Like their second generation TT bike (the first had well-reported issues). Maybe some of their other stuff is ok too.
