DAB isnt' too bad in my opinion. I have a personal Goodmans radio and sounds good. When it is a nice sunny day, and there is no work, I take both my radio and a pair of PC speakers into the garden.
Unfortunately, DAB+ will not be around for several years. (Well... not here in the UK thats for sure). If DAB+ came out now and DAB ended it would mean existing non upgraded receivers will no longer work and everyone would have to go out and buy a new DAB+ compatible radio. Yes.. go out and buy a DAB+ receiver but it will be years until we will get it.
