social media questions

there are a couple of social platforms I'm thinking of getting but I'd like others' opinions first to help me decide if it's a good idea or not.

1. Bluesky

I heard it's like a retro social app, which sounds cool. I read the reviews and apparently there are a couple of glitches. For those of you who've tried it, is it worth getting?

2. Bereal

I feel like this could solve my issue of always comparing myself to others. is it a good idea?

3. Letterboxd

I love movies! Is this app fun?

Thanks in advance!!
