(I've disabled this feature in my main editor for a long time though, so I'm used to hit Tab/Shift+Tab as many times as needed when pasting)
I much prefer working in languages wherein the series of tokens absolutely defines the semantics (as opposed to Python where the series of tokens + the context define the semantics)
- make it easy to write and to read at the expense of having complexity in the parser / implementation. Programs (or documents) are written and read a lot of times, it's worth optimizing, as long as it does not make the implementation unmaintainable. I'm saying that as a writer of several manually crafted parsers.
- avoid ambiguities in the grammar at all cost. They just suck for every party involved.
As for indentation vs braces to delimit blocks, I practice both and don't really have any preference.
