Attack on Titan and demon slayer worth watching?

I’ve watched around 50 anime in total, though I only remember the names of some. Others I wouldn’t count because I’ve completely forgotten about them. Every day, I claim to be an anime fan, but the only thing people ask me is, Have you watched Attack on Titan or Demon Slayer? When I say no, they respond, Bro, you have to watch them! You’re missing out on cinema! But I’m still unsure if I should continue watching them, and I don’t regret not doing so because they’re too long and would take away time from other anime. It’s not that I can’t handle long anime—I’ve watched Dragon Bal, One Piece, and My Hero Academia. It’s just that I prefer to explore a variety of shows rather than committing to lengthy series.
