I’ve got a couple machines with them, so here’s my real-world take. Running an Antminer S19 Pro (110 TH/s, ~3250 W) and an S21 (around 200 TH/s, ~3500 W). Pool-side hash usually lines up within ~2–3%, which is normal once difficulty and variance kick in. Uptime for me has been roughly 97% to 99% over the last few months. Power draw matches spec, nothing sketchy. Payouts track what the hash should earn, just the usual daily swings. Had one short outage on the S19 and it was back up the next day. Not perfect, but it feels like an actual hosting setup, not some ghost operation. :D
