Of the two, BDS is better. The BDS shocks and springs are better quality and ride better. I was pretty much the same situation. Mine is a DD with some occasional off road. I wanted to do it right and have a good ride. I considered the RC but it was hit and miss in a lot of threads so I went with the BDS. You won't find anything bad about BDS. You can get the BDS for under 400.00 and if you have any tool and are semi capable, installation of a basic lift is very easy.
