The entrance and exit pupils of the symmetrical lenses for RF cameras are about the same size - hence no distortion @ any ƒ/stop and focus distance.
With asymmetrical wides for SLR (or RF), the pupils are of different size - hence the distortion with variable form, tied to focus distance etc. etc.
In case some magazines in the 1960's said otherwise because their advertisers asked - it's a free world that runs on money.

No... I own the above lens (the retrofocus, SLR one) and it is indeed free from distortion and sharp to the edges, for all practical purposes and practical shooting distances. Not theory but actual, usable results.
The world has moved to SLR long, long ago. I understand there rangefinders can have their advantages, but "distortion free wide angles" are not a rangefinder-exclusivity anymore.
The Hasselblad 903 SWC is rectilinearly correct and it is not a range finder nor nor an SLR, but it is a MF camera.
In 1946 the first patent for a new kind of symmetrical wide-angle lens was applied for by the Russian lens designer Michail Roossinov. It looked as if two retrofocus lenses had been combined with the rear elements together and thus had a symmetrical arrangement of positive refractive powers close to the aperture, surrounded at the front and back by strongly negative menisci.
As of 1951, Ludwig Bertele carried this idea further and designed the legendary Biogon on behalf of Zeiss...

Regading rangefinders, my favorite one is the Kodak Retina IIIc. I love that camera!
After getting Leica M film camera I would not take any other RF, not just for free, but even if I paid to use it. Waste of my photography time.

Do you guys have any experience with screw mount lenses? i see you can get nice focal lengths and F numbers quite cheaply on the ebay, and how important is sharpness? i know that sound dumb, but how much detail can say tri-x 400 resolve, id be planing on using a fast noisy film elusively.

A Retina in the pocket beats my M4 left at home.
I'm after getting distracted by some leica m4/4-2/4-p. If you were to pick one leica for life under the 6/700 mark, What would it be? I read that the m4s can't be adjusted, And what they go out of wack you need a new part, but I've also read that the steel parts are sturdier, which last the longest after a CLA?
also whats with ''simplifying the range finder'' can i still nail focus with a f1.1 50mm?
In the pocket? No doubt. For in the pocket I used to have XA, BTW.
Some people swear the only authentic Leica experience is a Barnack with a 50. Others say it's a double stroke M3 and yet more say it's the Leica lenses that make the brand what it is and everything else is a half-measure. Really, it's what you make it. Unless you're buying from a dealer with a returns policy, it makes sense to put a pot of money aside for a CLA. Rangefinders go out of line, curtains get holed, shutters cap, it's what happens to decades old cameras and if you're not technical the fixes cost £$£$.I'm after getting distracted by some leica m4/4-2/4-p.

Retina for the win. The Retina IIIc has an excellent f2.0 lens, 50mm instead of that wide thing, more precise rangefinder, full manual control, and more beauty and smoothness.
Instead, consider a Canon 7; you can use Leica screw-mount lenses with that.
