I've only had the angus burger in canada so I can't speak for anywhere else but I actually quite like the angus deluxe.
That said, I also liked the brief stint that we got the chicken mcbites- namely the habanero ranch sauce - it was actually spicy !
I imagine we should get some of this up here in a few months. The jalepeno angus they have is actually the weakest angus I've tried. The jalepenos aren't that spicy but they speed up the mcshit that inevitably follows any mcdonalds consumption
