Quite a few people seem to like CoPilot since its so cheap, but I haven't tried it since v7. It was pretty nicely polished back then and worked good. I'm not sure if it has TTS or not.

iGuidance 2009 seemed to have jerky motions but it had TTS and the interface looks dated.

iGo has a nice interface, good POI's, and pretty good maps, but you have to do some hunting for this. It can also do TTS with some hacks.

I always go back to Garmin Mobile XT though. The maps are just as good as the standalone units, same as the POI database. The driving movement isn't as fluid as iGO since it updates every second or two, but still good enough. The thing I love about it is the online features. You can have it check for traffic (but it only checks it while calculating a route, not during the route), and you can use Google Local Search. This makes your POI database virtually endless since the online version is constantly updated. This feature alone has helped me out when the POI database was outdated. Sure, you could load up Google Maps and search that way, but its nice having it in one app. It can also check gas prices, weather, and flight status. The downsides? No TTS, not fluid driving movement, and when you guy it you have to use the SD card it comes on unless you find a way to unlock it.
