I'm a fan of Holeshot tires. On the other hand, tons of people like both and both have won championships in different types of riding. My recommendation is to buy whichever is cheaper for the size you're after. Fwiw, Holeshot MXR6 provide enough forward traction for most bikes up to 65hp. You should be fine.
Another alternative is Ohtsu. They'll outperform most non-paddle tires in a straight line and are a very balanced in other areas. http://farmandsandtoys.com/ocart2/categories/tires-wheels/honda-radial-tires-20x10x9.html
Also, I'd use those guys for anything that KOR doesn't sell. I've been using them for years due to their customer support, pricing, and reputation.
