You’ll probably get about 100 people to come on here and tell you to go with the Kosmic, since its an OTK product and without a doubt the hottest chassis make right now, BUT the Haase kart can be fast too. Who is around to support the brand in your area is probably more important to you. If there is a Haase or Kosmic dealer that is friendly and willing to help you get it dialed in and get you access to parts at a fair price, then that should play a key role in your decision.
Best of luck!
