I recently read a comment on a Leica review, to summarize, it stated that the Leica won't make you a better photographer, but you'll enjoy it more.
Thought about this for a moment. It's not a true statement. If a camera creates an environment that you enjoy more, is more intuitive, engaging, etc. it will make you a better photographer.
I come from the graphics side of the ad world and the Apple v PC debate, which is now mostly played out, is a perfect example.
i don't see much similarity between camera vs. computers, but if you want to talk about it...
For more than a decade the PC provided better performance and lower cost (and the same software).
that is still true in 2020, windows has nearly 80% of the desktop market share:

apple products are ridiculously overpriced, that hasn't changed at all.
But, walk through any creative dpt today and you will see there is no longer a debate. Apple's focus on interface and commitment to the creative process won the day. They priced higher, ran slower but, in the mind of the creatives, empowered a better result.
apple has a history of abandoning it's creative tools, for example where is quicktime today.
when apple released fcp x back in 2011, they changed the interface and screwed up editing basics like no multi-cam editing, can't assign audio tracks for export, can't import projects from fcp 7 into fcp x, etc... it was not a happy time for creatives, many left apple and didn't go back.
to sum it up, market data proves that the vast majority of camera owners don't want leica, just like the vast majority of desktop computer users don't want to buy overpriced apple computers.
