All depends how much the ski costs and where you are going to paddle it.
The performance is stronger and lighter, but more expensive. Once on the water there will be little difference for a beginner. If you can carry it without a problem I would go for the Club, if it has the side handles that should be easy to carry.
There are also not a lot of second hand V8`s for sale so you might wait a long time to find a Performance model.
