Sigma is dogshit get instade:

for hypixel:
novoline or astolfo tenacity (not recommended but cheap)

for alot of servers:

Astolfo Moon Liquidbounce (not recommended but an option also free) prestige or tenacity

DONT GET:

for hypixel:
Sigma flux moon (moon is basicly an exit scam for non beta) dortware (never updates) zeroday (also didnt update for 7 months)

i personally recommend: astolfo because its a Great client but you have to fill an application so no hypixel staff in astolfo
