Don't think I've come across the single-width RCBO devices. The regular double-width bolt-on types have been fine.

I think one of the latest Crabtree or MK range has clip-on breakers, but I've not run across any of them as yet. Call me old-fashioned, but I prefer C/Bs which are securely bolted to the busbar. Do you know the old Crabtree C50 range? Well-built, solid, and reliable.
