I have both the C12 (older version) and the T12 (older style). They are both awesome drills. I think this will depend on the type of work you do?? Also, will this be your only cordless drill or will it be supplementing, or complementing another drill? The newer drills are actually 10.8 volts. The CXS, although very small and lite, has some limitations in the chuck capacity (3/8), and will not accept the eccentric chuck. If you will only own 1 drill I would recommend the C/T style drill. Happy drilling!
