I've seen various posts about this and reviews conducted by Github etc, most of it seems to boil down to developer background, so consistently it seems to be those coming from frontend javascript like myself prefer tabs, which probably accounts for why overall the 'spaces' devs get paid more. There's still plenty of well known libraries and frameworks using tabs, so it will never go away and it's usually a case of letting the IDE take care of it so it doesn't matter either way.
I created all the repos we use at work so I called dibs on tabs
A much more interesting argument to have these days is about trailing commas and semi-colons!
