My pennies worth FWIW:
I've owned countless waterproof jackets over the years from utralight to 4 season laminated. ALL of them, once they wet out, will sweat. Not just Goretex, but Pertex, Event and similar garments, although some do have better breathability than others. None will keep you working up a sweat when climbing steep ascents or backpacking.
Still, I keep returning to Goretex as imho, a good 2.5 or 3 layer remains bombproof water tight for years. Paramo are good to be fair but they're also very warm to wear and more a winter jacket over base/mid layers. Way too warm for summer/early autumn work but they do wick incredibly well. As stated in a previous post, they won't stay as watertight though as a decent goretex.
These days I have two. One is an old 2 layer performance shell Berhgaus which is nice, light and very packable. It gets washed a few times a year and re-proofed. My jacket for serious weather and the fells is a Mountain Equipment Makalu 3 layer in the new ePE Goretex. Had it up in the fells this year on blustery wet days and kept me bone dry BUT you need to have both underpit vent zips fully open unless stationary or aren't exerting yourself (always look for pit zips on a waterproof). Also, pointless imho having hoods on heaver denier jackets like this as you're better off with a waterproof lightweight hat otherwise I've found unless stationary (camping etc) you'll overheat unless pretty chilly.
The important performance aspect of modern waterproofing is how long that they can keep the outer layer from wetting out. Whilst they bead water up, there's enough of a moisture and temperature gradient to breathe well. As soon as they wet out, the negative moisture gradient then prevents breathability and you sweat. The problem with the newer PFC free DWR treatments is that they don't work anywhere near as well as older ones because they tend to wet out sooner than the older PFC based treatments. You also need to wash them more regularly (every 3-4 months if in regular use) and reproof to maintain the DWR. The elephant in the room here that no manufacturer likes to admit is that with repeat washing, the internal seam tape will start unpeeling and need new seam tape applied. Typically within 3-5 years if washed more than a few times a year. They're all pretty similar in that respect irrespective of cost. My old Lhotse jacket eventually went this way after 6 or 7 years.
In some ways you're better off with a rain poncho as you don't sweat anywhere as much but they're a pain if the wind gets up.
The secret is really to be careful with base layers. Always wear decent lightweight wicking breathable long sleeve base layers and perhaps a light fleece when colder before slinging waterproofs on. Any sweat will migrate from these to the inside of the jacket but you wont feel clammy as a result. Worst thing is to wear cotton near your skin, as that's a recipe for hypothermia of you're hiking the hills on cold weather. It gets wet and stays wet so you freeze.
There's no such thing as a free lunch with waterproofs, but for my money I'd ideally have two to cover year round outdoor activities when I'm hiking or backpacking.
For three seasons, Rab's Firewall or Firewall Light (smock) won't break the bank ad breathe better than most (20,000mm hydrostatic AND breathability). Great jackets which'll keep you dry. They're both very light and pack small. You might see 4 years from those used regularly before their Pertex shells start to leak a bit. The second is the Mountain Equipment Makalu or Lhotse for colder weather. The Lhotse is basically the same as the Makalu but replaces the whole 70D shell with liighter 40D panels on low wear areas. These are still favourites amongst mountain rescue teams with good reason. There are other makes which perform similar but I get on with their fit well and they're build quality is up there with the best.
then you run the risk elevating to a degree!
