(1) In theory, QucsStudio kernel simulator might be different to Qucs' one (qucsator). In my experience transient simulations usually converge without problems.

The main issues I get take place in harmonic balance simulators. (2) QucsStudio does not have native installer for Linux. So you depend on wine.
