controllogix is much more powerful and much more expensive. It really depends on what you are trying to accomplish, if you are trying to decide which platform to go with. both use rslogix 5000, which IMHO, is the best plc programming software available… by far.

If you are doing small size projects and discrete machine control the Compact Logix is a good choice you can use the L3 series processors and connect other I/O to the CPU with Ethernet. I have used the L4x series processors for motion and some medium projects. If you want more detail send me a reply.
