The short answer....no, it depends on what you want to do with it.
The main difference is that traditional BJJ is taught wearing a gi and uses the gi for some techniques. 10th Planet is a no-gi(not wearing a gi, thinkin MMA) grappling system.
Having said that, both can be used very effectively and have different things that they excel that. Learn both if you are able, learning more arts has never hurt anyone, ever.
The one thing I would mention, is that in order to really be effective in 10th Planet, you need to be quite flexible. So stretching is an absolute must, you need flexibility in tradition BJJ as well, but not as much. However you don't need to be flexible right now, stretch every day and you won't have any problems with the system after a little while.
