Disclaimer, I'm a SEOS fanboy and I've only briefly heard the B212. But I like to think I'm a fanboy because it's a good design...
One of the added values of a SEOS design over the Berry is the horn type, which is oblate spheroid and also super elliptical. So you have an extremely low diffraction horn with close center to center spacing with the woofer. You also have a horn throat that is angle matched to the exit angle of the compression driver.
On top of that you have a cross over designed for home use rather than pro use. There are certain trade offs made with those goals, one of them being that the Berry probably crosses over higher than it should for true high fidelity. I've blabbed on about this in this thread before so I'll spare you the details.
One last difference would be the quality of components. You get a titanium diaphram in the Berry which can ring. The woofers in the SEOS designs are superior, so less distortion and better bass capability. And the port tunings are lower, so further away from your subwoofer XO.
I will concede that the details that separate the two speaker types are subtle and not easily heard without time and experience. They're not readily noticed on short listening sessions, and could possibly even be mistaken as better sound when the opposite would be realised with time. For instance, the speaker with less baffle step compensation may sound louder and more detailed, but two weeks later you may change your mind.
No doubt though, the Berrys are incredible value. I mean, I could not build a pair of speaker remotely like it for the price.
