I own two suits. One is the RB2 4/3 hooded and I recently got the RB1 3/2 Accelerator. A few things I love are: 1) the sales and price points; 2) not all sizes across brands are equal and Buell is one that fits me better than others (though my head is a little too big for the RB2 hood); 3) it is relatively easy to get the over-the-head chest zip on and while it doesn't stop all water from getting in, it is still more secure than a back zip, IMO. Things I am not too jazzed about are the knee pads. For some reason, they rub on my knee kind of hard. The 4/3 affects my left knee and the 3/2 affects my right knee. I notice it more when I walk vs surfing but I had lingering soreness after multiple sessions with the 4/3. I have only worn the 3/2 twice and I really liked it but the gluing on the chest zip doesn't look super secure. It held up the two times I wore the suit but even before I put the suit on, it just looked like it had been pulled a lot or something on the edges. See photos.
