> Remember to use lot of flux.

Agree with your post and this part especially. More flux means easier work, but more mess to clean up when done. Flux pens are practical.

I only used hot air for removing parts, but the techs who controlled it well absolutely loved it and were insanely productive.

I solder QFP by dragging a “saturated” tip across the leads and then wick up any excess solder if needed (e.g. if I bridged/shorted a few legs).
