Can't help for readers in Poland, but in the US, all I ever use are GRK screws, which use a variety of different Torx sizes.

I primarily keep stock of their 'cabinet' screws which have a washer head useful for mounting all sorts of things and their multi-purpose framing screws. I'll buy their trim screws as needed.

They are excellent fasteners and they're readily stocked in Home Depot near me, which is a big positive.
