Yeah, or even Qt, since their UI toolkit is also highly optimized for all kinds of plattforms. The advantage of the blender approach, of course, is that the app feels the same on every platform, since it is not bound to platform-specific UI requirements. So it doesn't end up in an uncanny valley, where it is kinda like the native UI, but not quite like it.
