This is a tough question.. If you need to consider a tracker in terms of content, one should have to put what.cd at the top of the list. However, the staff of what.cd is a real ***hole (well if any what.cd staff is reading this, you guys can PM to learn what the hidden word means) and once in a sudden, you may find your account getting banned for no reason or just for surfing over TI.org... So I would say, waffles is a lot better. At least you wouldn't get a ban for surfing over this site.
Seeding is never easy on the trackers so that shouldn't be a factor for comparing the trackers, unless one offers freeleeches, etc.
