I used to go with the very default of "light mode unless the application is dark by default" (for example, I wouldn't switch Discord to light mode, I just accept any theme/mode I get) but over time I grew to prefer dark mode. Easier on the eyes for me nowadays.
I do find all the light mode hate a bit annoying though. All the "flash bang" comments get boring after a while, even if I'm not the one receiving those comments. To clarify, I mean this when someone shares a screenshot or something, not in a general discussion about modes like this thread.
