I think both are very good to drive just the X6 was more appealing at the lower price and became very popular because of it and it's slightly easier drivability, the S2 when it has a good setup has looked excellent and didn't lack at all just not enough people bought them to give them a good chance,
The pros and cons of both cars in my eyes...

the s2 is very expensive to buy straight off but you don't need any upgrades for it apart from losi shocks

the x6 is cheaper to start off but in the long run your going to most likely want several of the upgrades that some say are essential some don't, that the team drivers run to get as close to their setups as you can which does get expensive... losi shocks, espeed hangers and tplate, bk2 axles, roll bar for some tracks, dms shimz for ease, kfactory front shock tower for durability etc etc and more which ends up being more costly than any car I know of!

More people run the x6 so parts support and setup tips are quite easy to get hold of where as the s2 there arn't so many drivers to get setups from but parts support is just as good in my eyes as the car uses alot more parts from the b4 which obtaining those is easy, the only s2 parts i can think of that you could break is the rear shock tower or chassis which are the least likely parts to break.
