C210, TS100, and T12 tip based irons are cheap now, why are we messing with the rest? C210 appears to be the new hotness a lot of irons use, but larger tips can be hard to find and you generally want a large tip for through hole.
It also has some misinformation about lead free. Leaded flux is not great either, if there's a difference at all:

Lead free is the only solder I use. Soldering spits tiny balls of metal everywhere. Your brass sponge gets full of an awful dust. I do not want a fine powder of lead on my desk.
