I have an Ersa iCon 1 and I absolutely love it. I would probably feel the same way about a JBC I'd guess. Two things I like better about the Ersa are the iron/handpiece is much nicer and more ergonomic, IMO, and the lo med hi heating ramps to make the PID more or less aggressive. On low there is pretty much zero overshoot on recovery, and on hi it matches the JBC for heating up time, although also for overshoot. The Ersa i-Tool iron is 80W continuous and 150W peak, very similar to the JBC (80 and 140, I believe). It was not easy to find in the U.S. though.
