I don't know. I like all the fonts, they're good. But looking at them for long periods of time makes me tired of looking at them and I just need to switch. You might as well ask me why I get tired of a certain food if I eat it too often.
Oh, OK. I asked, because sometimes people doesn't like a certain aspect of a font and can't stand it, and need to switch. Also, I'm also the exact opposite of you. I can use a font I like for a decade without getting tired of it. Same for a good color scheme for my terminals / IDE.
So it was a genuine curiosity of me. Sorry if it sounded rude or accusatory or similar.

I like to solve some problems once, and once I solve them sufficiently, I don't prefer to touch them, so I can focus on other things. It's not that I don't look for better solutions, but I don't actively seek them.
Same is true for tools. I prefer to master a single tool over the years to jump from tool to tool.
