I used an AVIAT 617 for my writtens, and passed them all first time. The odd real bastard question, I drew an A4 sized triangle of velocities on the exam paper!
Nobody at CAA or EASA cares which specific form of Flight Computer you take into the exams. It is *assumed* that the CRP-5 is what was used for setting the exams, but I suspect that may just be rumour anyhow.
The AFE flight computer is a nice piece of kit, I've never heard any complaints. There are also various American variations, usually called E6B.
