I think I need to hit Patterson again, but maybe not alone.
If you do a lot of freeway I'd imagine the CRF300 would suck, I was very impressed with the bone stock one I rented and road in Costa Rica, even with my fat ass and my ~50lbs of gear it was happy to haul me around. I did have to wring it's neck properly to climb steep hills and I was going nowhere near US freeway speeds. I'd guess there's some software to uncork the motor a bit, and that plus some aftermarket work for the suspension it'd be a very fun bike.
That said I am about to embark on a ride to Nevada on my DRZ which will involve a lot of freeway and I'm not looking forward to that part. THe bike does well enough, but I hate smoking dirt tires just slabbing.
We're opting for the NVBDR + the first two days of the SocalBDR tacked on so we can play in deep sand (for some reason) because a certain riding buddies baby date pushed up our itinerary ahead of any chance of the snow melting for the NorcalBDR.
I always lust after something newer, but then I get on the DRZ and I'm reminded of how fun it is to ride...
