I can't talk for the XXXS or TC4 but the Cyclone S is a great beginner kit.
Our club run a starter spec class using the RTR Cyclone S and it is one of the most fun classes to watch. This past week I borrowed a car from another user to run. I had a blast and the racing was very close because all the cars are matched for speed.
On another occasion, one of our best drivers borrowed a car to run in the stock 27 turn class. He changed the motor, speed control, tyres and batteries and ran the car. He ran the standard kit springs with the standard kit shock oil in them and finished second out of about 25 racers.
The main weak part of the car is the front C hubs and steering knuckles. I highly recommend buying a BRP(I think that's the brand) front bumper for a TC3 and modifying it to fit to cut down on breakages.
Apart from that, the kit is sweet and is completely upgradable to the full Cyclone.
I'm not a grown man playing with toys. I'm a hobbyist.
