This makes me want to write a post about the rabbit hole that is icon optimisation. It drives me insane when websites suffer from layout shift simply because they are not inlining their icons, for one.

I find the site very user friendly as it lets you customize the stroke's width, color etc, see how it looks like and copy the modified version.
Honestly, I always default to material icons unless a project calls for a very specific style. The coverage is just so dang good I rarely find a scenario without an appropriate icon and the style is neutral enough to blend in with a number of UI designs.
I used them for my offline text editor, the result turned wonderful (icons wise)

Most of my Websites/Apps don't use rasterized graphics for design anymore, SVG + CSS gradients/backgrounds & effects seem to handle everything I need.
But other than that, I also usually default to Material UI Icons.

Not a deal-breaker entirely, but for my own things I like differentiate.
Most users will not care if they have seen a map icon in another app before anyway.
