That you loved shooting with it, however, says it all. With you in mind I googled famous Leica users and came up with an article by Ken Rockwell.
Cartier-Bresson and the LEICA
Photographic icon Henri Cartier-Bresson was known for using only one camera, a Leica rangefinder, and one lens, a 50mm, for almost all of his life's work.
Photographers have always realized that this allowed him to focus his attention so that he always knew exactly what would be in his frame without needing a viewfinder. He could walk the streets, draw his camera up to his eye and shoot, all in one smooth, unobtrusive motion.
After many decades of thinking Cartier-Bresson shot with just one lens because it let him shoot faster and smoother,
I realized that Cartier-Bresson was, duh, a journalist. Journalists don't get paid anything. They aren't the rich hobbyists who buy Leicas, romanticize about the fascination and unique "Leica look," which is how the cameras look sitting in their glass display cases and Danish Royal Wedding presentation boxes.
Cartier-Bresson obviously went to a Parisian camera store, and bought his Leica and lens after much saving and scrimping.
He liked it, and when he went back to get another lens, found out the price, shouted "Merde!" and promptly walked out. Cartier-Bresson never again returned to a camera store.
That's why he only shot with one lens his whole career: it's all he could afford.
Why then did he shoot what seems like such an expensive camera? Cartier-Bresson started shooting in the 1930s, at which time Contax was the good camera, and most serious impromptu photojournalists (all three of them back then) had to settle for Leica instead. Nikons and Canons hadn't been invented.
When Cartier-Bresson walked into that camera store in the 1930s, a Leica was all what most people who had to work for a living could afford, if anything. Cartier-Bresson was a just a journalist, although he is now an icon. For all I know, his portrait may already grace the 100 Euro note.
