Depends on the group, tbh. With my family, they prefer everyone be sort of bad at the game, they don't like very complicated games, they don't like games with competitive mechanics, etc. They like very reliable "we have always played these games" sort of games. Growing up with them, I didn't even really think about the fact that you could break out a board game for an occasion other than a family gathering, because no one ever played them outside of holidays, etc.
With my friends, one group is SUPER into board games, so I'm currently probably the worst at them, but I don't care if I win or not? So I think they actually wouldn't mind if I was more competitive.

These people are probably my favorite to play with. And everyone has a different type of board game they're better at. I'm decent at resource management ones, one friend is great at deception games, another is great at puzzlers, etc. so we play all sorts of games and no one is handily the best at all the things.
I have another friend group who is in the middle of the two, where they play a lot of games, but they don't really like it if you're really good at them. Like if you bring a board game to the table, they don't want you to win, like it's "cheating" or something to be good at the game you own. I brought a very simple roll and write game once (if you're not familiar with that sort, think Yahtzee, where the dice get rolled and you write down how you apply them to your sheet) and one of them was really bad at it, and made it out like I hid the rules or something.
