I've got the B3 in Polished Black in mine. The quality of the S2T paddles is excellent. Pictures really don't do them justice, They are much better in the flesh. Also arrive very quickly from the US - delivered within 4 days of ordering!!!
Style wise they all look nicely oem, but I think style choice also depends on your natural hand position on the wheel, with B1's suiting the traditional 10-2 position and the curve echoes the curve of the wheel. B2 and B3's suit a slightly lower hand position 9-3 and that's where my hands are when using paddles so they suit me plus I prefer the shorter style of them. The shape of the B3's along the top of the shifter nicely mirrors the shape of the black trim.
On the R forum these are being discussed and someone has posted the link to an open group buy (not specific to that forum) which reduces the cost by $50 roughly, so maybe you could get in quick buying via that link. See the thread here
