The Tomahawk plane is quite a bit larger than the Skygate Hawk, which is what the Comp ARF Hawk is modeled from. I have been flying my Skygate Hawk 4 years now. Initially powered by a JetCentral Rhino, now upgraded to a P-200 with full bypass.

If you're planning to compete in WJM, the 160 size is adequate and meets weight requirements. But, if you're looking more for sport performance, of the two turbines mentioned I'd go with the Mammoth. The Hawk will never be a speed demon, it's a fairly draggy airframe. so you will need the extra power for good verticals etc. I do not believe the Mamoth could Vne the Hawk straight and level, but you would need to use throttle control coming out of a split S to avoid tail flutter.

I'm interested to see what the weight of the Comp ARF Hawk will be. A few extra lbs over the SkyGate version would actually provide a better flying jet, I think. Also, the enclosed bypass designed and produced by Marc S of GBRJET would be an excellent addition.
