I use the default one. Thankfully the brightness of my laptop is good enough for my eyes. I actually tried the dark theme for a few days and I ended with more reading problems, specially when it comes to formatting. That's my experience tho, to each their own.
Dark theme, definitely, since I usually use the laptop at later hours.
I wish there were different hues of dark mode, though. I have a browser extension that applies a custom dark mode for websites that don't, and I always configure it to have a warm palette since it's easier on my eyes.
I use dark, better readable and better for the eyes, as white is to bright.
not that I have Eyes issues, but something else that I like to avoid and
I like dark themes (like black) as I use it alot in creating text effect and
UI creation =)
