It's difficult because we haven't seen 2019 in person yet. I voted for 2018. When they previewed it, I thought they were pretty mediocre, but after watching them in actual game play, they turned out to be my favorite. It's a really clean look.
We're actually on a pretty good run IMO - I really didn't love 2012-2015, but since then they've been good. Fewer crazy things like red/black helmets. I think I like 2019 best, but sometimes they look better or worse in an actual game so we'll see.
I'm going to still go for 2013 on at technically. To me, the last four don't *really* count as alternates. They basically just changed the colors around without making any real design changes or re-did an old jersey.
I think 2019 and 2016 are really sweet. But - to me - they're not quite in the same category. I think I'd rank them both ahead of 2013 as far as just which one I like better. But Adidas does a lot better job of not screwing things up when they just tweak something we already had instead of try to come up with something totally new.
I guess I like the ones that aren’t super different from our normal ones. Probably because most of the very different ones have just been ugly. I think it’s possible to create a different one I really like; they just haven’t yet.
