Technically no noticable difference if you disabled the XP theme, I still have a Win98 on MS Virtual PC and it works very well.
Although Win98 was not supported anymore, it still runs faster than 2K/XP, and most Win32 API are frankly the same, unless you're using NT5/6 specific APIs, 9X still does the same thing and B+/B3D bahaves the same.
