Joel, I think your impression comes from several areas. Some more valid than others.
In the last ~3 years we've seen a lot of light PU WPB jackets with very thin coatings, which seem prone to delamination on the shoulders (presumably from pack straps). I think the frequency of this has been overblown, but it is a relevant concern IF you wear your jacket a lot.
My own experience is that comparably light Goretex does not have similar issues. These start at 250 MSRP, generally. My 6 oz Haglofs Ozo (Paclite) is a little over 2 years old now, has had a ton of use, and functions as good as new. Yes, Haglofs doesn't make it anymore. Sadface.
I haven't heard of any Event (or the more recent knock offs) delamination issues, but there are not infrequent reports of wetting out not due to DWR failure. I'm not if this is the membrane being contaminated easily, QC issues, or something else. Probably all of the above. In any case, I still consider these fabrics less reliable than G-tex.
The final issue is that all WPB jackets have fairly acute performance limitations, and manufacturers have shot themselves in the foot repeatedly by claiming otherwise. Most egregious of this is a lack of education on how and when to maintain DWR treatments. I would estimate that 95% of the "worn out" WPB jackets in the world just needed a simple DWR reproof.
I cram my Ozo into tiny spaces in my pack, roll it tight, sit on it, and generally don't worry about babying it. I do not believe this detracts from longevity.
