At my university (Surrey), the computing and information technology bsc shares 6 out of 8 modules with the computer science bsc, but takes 2 from the business school instead of a couple of the computing modules, so they take an accounting module and a management module instead of an assembly programming module and a mobile development module. Overall I actually think that the computing and information tech bsc is actually the better course, but of course this varies by uni. I doubt it'll make much difference which you really take, as long as you do well in it.
