Induction curie point machines don't have closed loop control in general (at least not the kind that involves anything past the tip) The main box just blasts RF energy down the line, the tip either absorbs or doesn't absorb the energy based on its temperature set by the curie point of the magnet in the tip. No thermocouples involved.

Be aware that JBC has two categories of soldering irons with very different heating times. It was mentioned in one of the threads here.

Well, JBC does have old-fashioned "classic irons".  As far as I know, all the temperature-controlled stuff is fast heating.  But none of the JBC irons use induction heating.

Check this thread. Clearly two different heating times for current JBC products.

Two seconds or five seconds, you mean?  Mine are up to temp by the time I get the iron and solder in place (T245 handles).  The time is also going to depend on the tip.  Some have "high thermal efficiencies", some have large mass.  Can't see that being much different with an induction iron, it's still just power delivery.

Come to think of it, the variety of tips available is another thing to consider.  There is not going to be a big variety in tips until a series of iron has been around for a while.  For example, Hakko has 10.4 and 15.7mm "spatula" tips for the FX-100 (in two temperatures, 400C and 450C).  Metcal looks to have 10, 15.75, and 22mm, JBC has 10, 15, 21, 32, and 37mm.  Whether it matters depends on the operator and usage of the iron.  Most people will be happy with a few typical shapes and sizes, but some will find extra versatility valuable.
