When I started to write in Python, I thought: 'I want to use braces!', now I fell good with indentation. I prefer this because braces can create confusion with other braces that you use for functions, lists, sets, ecc.
I prefer braces with auto-indent or beautifier. That makes it easy to identify matching braces. "Newer" editors also highlight matching braces when near one of them and the whole section can be collapsed.
You should always indent, no matter if you have braces or not.
As for braces, I don't care a lot. I like the cleanliness of Python, but missing braces are a lot easier to find than wrong indentation. I guess I like them.
Braces are most cleaner than indentations.Braces represent blocks and are more easier yo understand than indentations.Some people just use only one space as indention and It is very annoying to check the scope of variables in the blocks.So in my opinion,braces are more cleaner than indentations.
