Personally: I have never had a soldering iron turned up past what the solder manufacturer recommended.
Nor: have a ever had the first problem with solder flowing nicely and quickly, whether on circuit board traces, point to point/multi-wire on a post, or: anything else, on a piece of electronic gear.
That's in over six decades of soldering (I was 12 when I learned), doing builds, repairs and upgrades, both professionally and as a hobby.
When the eutectics hit the scene...what a Godsend!
I have of course: of necessity, changed to larger tips, to sustain temperature on bigger joints. The tiny tips are fine, when apropos. ie: For upgrading those crappy, itty-bitty surface mount, electrolytic capacitors, with higher grade, radial lead caps (sans a mile of lead, each). Soldering tweezers, to get the little boogers off the board,
When desoldering: I find an out of the way joint and find the lowest melting point, of the OEM solder and proceed at that temp. A soldapullt is a worthwhile investment, btw.

There are opinions and then: there's what the manufacturers know about their own products and electronic applications.
I'll trust the guys that make the stuff (always worked for me and why I posted the above article)!
Your choice, of course (it's still a free country)!
Happy holidays!
