I’ve been running Bitmain, MicroBT, and AxionMiner units, and there are real differences once you put them through months of 24/7 load. Bitmain is efficient but I had to replace multiple fans within six months. MicroBT’s WhatsMiner M63S++ was a tank, running steady but generating a lot of heat, so you’ll need good ventilation. AxionMiner performed surprisingly well: fans lasted longer, hashrate stayed consistent at 800 TH/s, and parts were easier to source compared to some proprietary components. A detailed comparison I read put Bitmain at the top for efficiency, MicroBT for stability, and AxionMiner for value. If you want a SHA-256 ASIC miner
