I thought Maxell had better balance than TDK, although it could depend on the preference of the equipment manufacturer, too- IIRC, some, like Pioneer, were biased for TDK. Sony would obviously bias for their own tapes but in my own experience, my JVC CD-1770 sounded great with Sony Ferrichrome tape when I recorded. For playback, Maxell was another good choice, but TDK sounded a bit weak on the low end.
I always liked the cassette recorders with variable bias with three heads.
