In reply to Irishonthewirral:
Like mentioned earlier, go for fit.
eVent breathes more, but needs washing more often, and is essentially the same material as goretex.
Depending on fit and budget, there aren't huge difference between the major brands in terms of quality. Most are using Gore-tex pro-shell or eVent.
Paramo is a tricky one in that it's more of a soft-shell, so breathability is better. All depends on your use. My only gripe with soft-shells is they aren't usually a fully weatherproof barrier between you and the elements. So if for some reason you're stuck and don't keep moving, they could be seen as a liability in a way....
But, it's all dependent on fit and function. Many people I know are happy with a good Paramo/Buffalo/VR top and keep a lightweight pac-lite shell in the sack just in case.
The layers you wear will also affect the fit + feel of the jacket too so keep that in mind, most good shops like Cotswold etc will be more than happy for you to try load on with layering systems too.
