Hey, I own a 04 TC450, wich I have ridden a coupple of times.
It runs really really well, and it starts fine even after a upside-down crash.
I've just got it right jets sorted out: 185 main 35 pilot needleclip:5'th (from top) It made it pull harder/rev quicker. Im pleased with it!
Unfortunately I've never ridden a 250-F of any brand, but if you are like me, you like the smooth kind of riding, and thats where the husky450 really shines I think. It's more stable than a KTM, and the TE450 won the enduro world champs. this year. Good luck.
