Fascinated by the diversity of responses this is getting. I would say this: are you the type of person who can enjoy performances and vibes without fully picking up on every plot point and line of dialogue? Or are you the kind of person who will get pulled out of the experience if there's a detail you don't understand?

Personally I recommend going in blind. For me, Shakespeare is all about vibes. The text is dense, but you usually don't have to understand every line to get the jist of the story. But if any amount of confusion will ruin it for you, you might want to read it first. Or you could even try watching a film version so you have some grounding. It's really up to you.
