What year is the RS? The older ones had a flex issue. Pre 2009 I think are the bad ones. If it has the power bulge I think they are ok. I had one of the flexy ones and it sucked but I also had/have a newer one and it was fine.
I had a F29 RLC on my Turner that was pushed. I really liked that fork, it was set and forget and never gave me any problems. Was good at everything I threw at it. I sold it to my friend and he still uses it.
I have the top of the line reba now (carbon steerer and crown). It is a highly adjustable fork. It takes time set up both the negative and positive air chambers for the riding style. At first it may seem like it sucks, but if you are persistent it rewards you with a fork that has nice small bump compliance yet it is able to take smaller/medium hits with ease.
All that typing to say, I don't think you can go wrong with either one. Just make sure you stay away from the older versions of the reba. I would also ask if the maintenance has been done on both forks. Fork rebuilds will add to your cost, especially if you cannot do them yourself.
