The C2 isn't much slower the the ST and for the price its a good little car with a 20,000 mile.... yes, 20,000 mile service interval to not worry about.

Is the ST better - yes, its bigger, faster (just) and nicer inside and (sorry in advance for any saxo drivers) doesn't have the chav image that I link to Citroen's hot hatches. I would have probably gone for the Citroen if it actually had a boot as its cheaper to buy, run and insure.

As for the Seat, I hear they're a good car but I've never driven one.
