I switch back and forth between peterson, goso and southord slimlines just depending on what I'm in the mood for. I have a majestic set aswell which I'm quite fond of, mind you it's mainly for the old-school look and feel of them

I don't have any hands-on experience with the other brands listed, but if I had to choose just one out of the sets I have, I'd go with peterson since they score high all round.
Great variety of picks, they're super smooth, and there's no beating those dipped handles. I can't imagine comfier picks... never any fear of bending them either, which is a plus, and their wrenches are fantastic too. To be fair, I don't use them very often, but if I could only have one set of wrenches it'd be theirs for sure. I know peterson picks are designed more for US keyways, but they can get around most stuff here just fine - although if it wasn't for the slender range, I might be swayed it get the slimlines instead for just-in-casies.
