Plunge Pro edges ahead on our weighted scoring, but only by 0.2 of a point — close enough that the specifics below matter more than the ranking. Plunge Pro costs $1,005 less — about 10% — so the question is whether what Chilly GOAT Alpine Glacier adds is worth that to you. They separate most on price (Plunge Pro), overall score (Plunge Pro) and minimum temperature (Plunge Pro) — those are the rows worth reading closely. In short: Plunge Pro for buyers who want a commercial-grade separate chiller; Chilly GOAT Alpine Glacier for buyers who want hot-tub-grade construction and comfort features.
