So, from a sample of two (one old, one new) you have reached a definitive conclusion? Hardly scientific.
The propensity of modern jackets to fail has more, in my opinion, to do with the trend towards light weight. It's hardly surprising if a 300g garment wears faster than an 800g one. The membrane is then more readily exposed to damage. I would however hazard a guess that, for its shorter lifespan, the modern jacket is a bloody sight more comfortable (=less sweaty). And, for me at least, staying cool under the jacket is more important than staying perfectly dry.
OP try Neoshell for the best breathability. Rab and Jottnar both make good jackets at differing price points.
