"not looking forward to the radio side of it"
You are on autopilot 100% of the time, which reduces workload dramatically. But of course the IR checkride is flown by hand. They can allow enroute sections to be flown on autopilot but you will hand fly approaches much better if you turn off the AP at least 20nm before you get there.
ATC ELP varies a lot. In N Europe it tends to be pretty good, and "native English" people are OK with it, especially if you had been watching Colditz
Further south it can easily be much worse, with France and Spain having swept ATC ELP comprehensively under the carpet. Of course if you are French or Spanish then you see no problem with English heavily accented in your own language (such is the nature of language). For some really poor ELP, as well as seriously dodgy phraseology, see this video
and this is typical of France. In fact I would say Spain has improved a lot since say 10 years ago, and same with Italy. Former Yugoslavia and south of there is pretty good.
