Gi or No Gi Grappling

Do you have to train in the gi to learn grappling? There are forms of grappling that don't require a gi (various forms of wrestling). I enjoy training in a Gi (as you know, I play Judo). The gi provides more handles and provides more control over an opponent. The gripping is different and you have more room for error in your moves. No gi has less grips and there is less room for error and less submissions available. In a gi, a lot more chokes, set ups, etc. To randori in a gi is awesome exercises as you develop the grip strength of a gorilla and this is useful in no gi. So, if you ask my opininon train in a gi even if you compete no gi. I personally think it is more difficult in a gi and more basic without.
