Why isn't XTB talked about more?

XTB seems solid on paper - FCA regulated, been around since 2002, commission-free trading.

But I barely see them mentioned compared to IG or Plus500.

Is there a reason they're less popular or are they just less marketed?

Anyone actually trade with them? How's the execution quality and withdrawal process?

Trying to figure out if they're underrated or if there's something I'm missing.
