If money is no issue i would go with the leica.
On the other hand I have seen people around saving money since years for their first LEICA - and than - they were scared to take the Leica on vacations etc. (Quote: "what happens if something will break - no I will leave the Leica at home....").
So they were scared walking with $ 8k on their neck - they were scared about any scratch.
They put funny LCD protections on their LCD , on the buttom plate they still got the foil protection - just in case they will sell it next year...
Sure the above is extreme and not anyone will handle his leica like this I think. But you will do, im quite sure, if you dont have the money to own a leica 😀
I am not a professional photographer, and this is just a hobby I have and love, so basically I for myself decided to stay with the RD-1 because i dont want to get back into the "loop" of getting every new year a new Leica model M9 -> Mx -> Mxx -> Mxx etc.
So If you can afford a Leica + Leica lens, go for it. Im quite sure it can be a lot of fun.
Just be prepared ..the next better Leica will come soon...
I can afford one , but I dont need one. My RD-1 is doing her Job since many years without any bigger issues.
