thank you very much tony for answering my question, it helps me a lot!
As you note yourself in your blog, even (especially?) Hät is unable to respect a similar scale between its different sets... Nevertheless it is undeniable that if the two manufacturers can be mixed without problem, their respective miniatures have a different "air".
On the other hand, thanks to you, I realize that I have missed out on a superb set of a late Roman commanding officer on horseback: it is surely thanks to your talents as a painter, but it is undoubtedly the nicest !
