I'll put them in categories for you, these are my top picks and are my top picks for clients, shaders and resource-packs.
CLIENTS: 1. LunarClient 2. BadlionClient 3. CosmicClient I usually use Lunar-Client for when I go on MMC or Lunar. I'd prefer Badlion Client for Hypixel and other 1.8 servers since I have more issues with Lunar, but hopefully when I upgrade I'll be able to use Lunar as I like it more. Cosmic-Client is my third favorite client since this is the first client I ever used and I did enjoy it but for FPS it's not the best.
SHADERS: 1. BSL 2. Continuum I use BSL more since I think it looks honestly amazing. There isn't much to say about Continuum it's good, and I'm able to run it slightly better on my computer but BSL is my top favorite.
RESOURCE-PACKS: 1. SPRING BREEZE 16x 2. Faithful 32x Both of these packs are used with the intent for survival or building. I really love BSL and Spring Breeze 16x as I think looks amazing. But I also love the mix with BSL and Faithful 32x as it looks equally as good, but I prefer Spring Breeze since it just adds more colors to the game.
These are my top picks for all these of these categories I can't wait to see what others post.
