I've had a Galaxy Fold 4 since release (last september), and I haven't personally had any durability issues whatsoever. The thing here, though, is that Samsung is scheduled to release its fifth generation folding device in about a month or so, while the Pixel Fold is Google's first try at a folding device.
The Flip and Fold 4 are probably the most refined foldable devices at the moment, and I've been really happy with mine. Google is a couple of years away from this level of refinement, so it doesn't exactly surprise me that the first Pixel Fold is "meh".
