The database is good. It's large, well curated and annotated.
The UI is terrible, a sad relic from the MDI era. It's absolutely _not_ quick (you can constantly see it repainting, for example), search is extremely clunky, tools for match prep are awful, and it doesn't really have any good learning features. There's some vaguely interesting recent stuff like novelty mining but it's very limited (and why charge so much for database subscriptions only to make people do so much local eval?)
I dunno, I still pay for it because the database is nice to have, but I'm always astonished by its success. YMMV.
