I mean, literally, the tips.
There is a lot of controversy about just what sort of tips is "right". I can't really say that, but I can tell you what I use and have had success with.
I prefer tips with a flat rather than purely conical tips. I have many, 11 including some very fine conical ones, and I use six or seven of them from time to time but of those I use four regularly, depending in the job.
I use a Hakko FX-951 station and T15 tips (a side note, I have an FX-88 which uses a separate heating element and tips that slide on it, the difference is enormous. The integrated heater elements are so much better.)
The four I use are these:

Left to right, for very small SMT work, the C1 "bevel" tip which had an 60° angle on a round shaft:

For small THT and larger SMT work the D08 (.8mm) "chisel" tip (also called "screwdriver") which looks conical in the photo but isn't:

For THT and other heat tolerant large sized things the D16 (1.6mm) chisel:

And, for large floods, big heatsinky stuff (think batteries etc.), bulk desoldering, etc, the D52 (5.2mm) chisel:

These are what I use, and what I would recommend if asked. I think a chisel tip of the right size, or the bevel at the really tiny sizes works better. I get better heat transfer, heat the component for less time, and find I can keep the iron in place more easily.
How about you?
