I take the same 4 or 5 bus routes and thats about it, so to me, the bookmarking feature is the most useful. I dont use the map at all (which seems to get negative reviews) so I dont have any input on that. In general its about ad accurate as the CTAs page (after all, it does get its info from there). As long as you know which route and stop you need, this app helps a lot.
