I used to delete bb maps the second I opened up a new unit (I get new ones very often). Then I'd install Google maps. Google has a couple more features. The reason I PERSONALLY went back to the BBmaps program is that a lot of apps-- the 411 apps mostly, that I use.... Interact better with the native gps prog-- bb maps, than anything else.
So the posters are right-- you should try both and decide. Based on your needs and the apps you use around it-- you may choose one or the other. But again-- on PAPER, as in-- feature for feature-- Google looks better, even though it isn't for some.
