I've coded in python for >10 years and C# for ~half of that. I prefer indentation-based control flow purely because it condenses code vertically and creates consistent indentation with actual purpose (many of the devs on C# projects I've dealt with have had inconsistent tab/space settings and no linting).

If anything, the one thing I hate about Python3 is dynamic typing - inferring datatypes in function bodies is great but strongly typed (and _enforced_) parameters and return values would clean up a lot of the problems I have seen, and created in the past.
