In the hakko line, fx-951 is the step-up which uses a heater and sensor in the tip (t15/t12 tips).

The alternative, for a hobbyist, would be something like this new iFixit iron, the Pinecil, Miniware TS80/TS100 or one of the variety of chinese irons from amazon and Aliexpress that take Hakko T12 tips (Quicko and similar).

On the high-end, professional side, it's JBC and Metcal. Expensive.

The handle is so light! Active tips! Heats up in 2 seconds. Goes to standby mode when you put away the handle to save the tips.

There's even a lighter compatible precision handle that you can buy.

Luke Gorrie posted a bunch of Twitter threads where he compare the sizes of soldering handles. Can't find it now but https://github.com/lukego/soldering might lead you to them.
