I like it with 90s and early 2000s circuit boards, where functionality was essentially the only thought given to their design.
As someone who's repaired his fair share of electronics, some modern boards look more premium than others. I don't like it if the board inside looks rather cheap, like with the Joy-Cons. The Pro Controller looks better, though (and honestly, a lot of what makes it look less cheap might just be going with a non-green board and covering more of the traces and solder).
I didn't vote in the poll because I don't feel either of the first two options properly conveys the nuance of how I feel here. I certainly did love my atomic purple GBC and N64 controller, though.
