Agreed, it's definitely a nice balance of accessibility and skill. Garegga is painful sometimes and APB is almost too colourful and comical given the other two games "darker" aesthetic. In saying that, I reserve judgement until this PCB arrives, however as it stands I would rate APB my favourite followed by Bakraid (thus far only played in MAME) then Garegga.

^ Also DO IT, Garegga is a brutal game... but satisfying nonetheless when learning it's complex scoring system. Plus it's surprisingly always been the cheapest of the trio, even though it's more legendary.
