Best GPS/Map app for Android

I tried out Orux a few years ago and didn't like the interface and lack of options.

The offline usage of Google and Bing maps is probably unauthorized. You can trick other apps like BCN and Gaia to use those map sources too, but it isn't officially supported because Google forbids this use.

I haven' used it again recently because I'm happy with the apps I have, but I may look at it again to see if they've improved things.

I use Gaia on the iPhone but my next phone will be an Android and I'll use Gaia because you can use custom maps with the app.

I create calibrated custom maps for my cycle touring trips and over the Christmas period I'm off to Burma. I use the Maps N Trax on the iPhone but it's got a steep learning curve and I don't use it enough to master it, so Gaia on an Android is the solution to my custom mapping problems.
