Lol I love it when Gaara and Kakashi fan boys fight against each other, it makes my day. Now to reread the Sasuke VS Gaara thread. 
OT: Gaara has much more fire power than Kakashi. His defence is also far greater than Kakashi's. I would love to see Kakashi out running Gaara's sand tsunamis, sand hands, sand bullets and all sorts of sand attacks coming from all directions (above, below, from the sides or from below).
Kakashi could win this if the starting distance is small though but Gaara could fly to the air to avoid Kakashi. If Kakashi's arm gets stuck, Gaara could crush it. Kamui could be a game changer though and due to hax of that technique, Kakashi does have his chances here.
I'll give it to Gaara high difficulty.
