Only true for the pure capacitive droppers ... how common are those compared to active converters (dimmable) and linear regulators (not dimmable, but not much flicker either)?

It all depends on your application.
If you have an existing fixture fitting for a conventional bulb, yes good replacement.
If you have downlighters , or ceiling fixtures or cabinet ligting or spots you don't need diffuse 360o light, you only need light shining in a restricted angle, so led smds are preferred.

The main benefits of filament led are great cooling conditions. No massive aluminium bricks around

Unnecessarily huge red text is foolish vintage crap.

What is the lumen output of the those filament bulbs? It's probably nowhere near what SMD led or incandescent bulbs produce.

They are a bit expensive, but Segula has a 40W E40 filament bulb.

I wonder if it's the filament or switching electronics which are the limiting factor in this respect.
