I like the Aussie and New Zealand accents the best, and I really like the way a Mexican/Spanish accent sounds too and it's the one I probably hear the most. Sounds very friendly to me in a way
Boston: Worst one for me, by far
Minnesota/Wisconsin: Shit sounds ridiculous but sort of hilarious at the same time, but most just annoys the shit outta me
Irish: Maybe one of the more unique accents out there but I really can't tolerate it for long
Hopefully no one takes any offense. I'm from Southern California and sound like a stereotypical stoner saying things "dude" and "bro" all day long and curse a ton which I'm sure some peeps can't stand, which is understandable lol
