Lunar client is technically better than Badlion, as it can reach you up to 1000 fps when standing still. If you use Lunar client or Badlion client you are going to want to be a Pvper. If you are a casual player who doesn't sweat at all then use vanilla but if you want to be more of a Pvper then get Lunar. I've seen Badlion and Lunar together, personally, I'd suggest Lunar (you can just look up a video on youtube to get a more in-depth answer on why lunar is better than badlion) if you want to play Singleplayer and Pvper I've heard that Badlion is better but I wouldn't know too well. Nonetheless only get it if you do lots of Pvp.
