Yes , Leica can not ruin your photographs like a nikon , I agree.
I used 5 III series Leica and a Leicaflex. There was no internet but seller of 50s to 80s camera journals and magazines. I had no photographer friends and working 16 hours a day 9AM to 1AM. So there was noone to Show my cameras. But surfing the 40 years of magazines , it apperared Leica was the best in 35mm. There was Ektar Linhof Shots , wollensaks , cooke , hasselblads and nikon lenses but best was Leica.
I am quite schocked when I saw Leica bashers here and the status symbol. No sir !
