I've used Better Bottles for a few years and like them. Soaking in Oxyclean or PBW cleans it, only once have I put a wash cloth in it to swirl off some extra gunk, probably could have soaked longer. The suck back on the airlock when moving the bottle is the only major problem- fixed with using the milk crate, loosening the airlock or they also make a dry airlock which works well, albeit it is expensive.
