Liang, You or Majed, Alqasas?

l'm currently enrolled in Liangs class, on Tuesday and Wednesday and I'm wondering if I should try to enrol into Majeds(Wednesday and Thursday) given his good rep, only thing is, pretty long day on Wednesday if I do, and I'm not sure if it's worth it? What's Liang like as a prof? If anyone could give any suggestions? I haven't been in school for a while (mature student) and I would like to optimize my chances of success in my courses. Any feedback would be appreciated.
