Project BM! figures being Bandai-Medicom collaborations and RAHs being the homogeneous Medicom figures ( some collaborations with THM)
Rah focus mainly on older rider and PBM mainly on newer rider.
Rah also have nicer box , outer layer they have diff design and inner they have something else.
Hehe the rest i dunno la

not pro in medicom xD

Just some add on point to differentiate PBM and RAH
RAH packaging will have smaller box but they have another outer layer to protect inner box, packaging from front is always a drawing graphics of the rider, and due to massive version release, we can actually differentiate between v1 and other version by the drawing, v1 always is the rider standing still like the picture hellforce bro provided, v2 onwards will have some pose.
PBM have bigger box and always use the photo of the figure itself with plain white background in front box, no double layer, but do note larger box doesn't mean more accesssories. PBM started since 2005 during the period of Kamen Rider the first, just as what hellforce saying, PBM only features new rider for once, hence during the same year, TV was showing hibiki, therefore, any rider series before hibiki are never been release in PBM, but it is not vice versa, Kabuto have been redesign and release in RAH series.
