Oh, it's been a long time :-), but I'll try to dig through my memory. I think I liked the Gerthsen, our Profs also recommended Demtröder, which was OK, but somehow I never liked it as much. In theoretical physics, Nolting and Fließbach were good -- though I cannot remember which topic I learned from where. I did my Diplomarbeit on spin transport in mesoscopic systems, and really liked "Electronic Transport in Mesoscopic Systems" by Datta, which at the time seemed to be the only accessible and clear writing on the subject. Disclaimer: I tended to go to the lectures very regularly, and mostly learned from there, so the books very mostly supplemental material for me.
