1. Bambu Lab A1 — best for most people
Full auto-calibration, 500 mm/s, a 256×256×256 mm bed and the most polished ecosystem on the market, with the optional AMS lite for 4-color printing. It's what we recommend when someone asks "which one do I buy?" with no further context — and most independent reviewers agree. And, for now, it's the only one on this list I (@marcojlv) have personally tested: I use it daily and, from my own experience, it's one of the easiest to start with.
