Yeah, this was definitely not the worst I have heard. Later his pattern radio work was quite smooth too and each round around was a nice concise "downwind, Cardinal in sight, option". In my experience it is talking to approach controllers where the language barrier really shows up. He was flying an aircraft that rents out of Nashua and so obviously is familiar with Class D operations.
But at least in this clip there are also a few weird things like him calling the tower "Manchester Tower" and the initially confused sounding response of "traffic... number 3..." (sounded like the mic was not keyed at the beginning).
I have no complaints as long as they are flying safely. None of the cases in my clip were unsafe whereas the guy who couldn't manage the right turn in the youtube video... yeah, that's actually a safety issue. Mentioning the wrong airport "Manchester Tower" is not nearly as bad as doing that on a shared CTAF. Here in the northeast there are usually a lot of airports sharing a given CTAF frequency.
