IMHO variety, at least among the more 'relevant' countries (I'll define relevant as teams that currently play in the top level of the WC or at least regularly bounce up and down), is sorta lacking when it comes to international jerseys.
It seems most fall into one of three colour schemes:
Red & White: Canada, Denmark, Austria, Switzerland
Primarly Blue with Red & White trim: USA, Slovakia, France, Slovenia
Primarly Red with Blue and White Trim: Russia, Czech Rep, Norway
Not saying I don't like the above jerseys, on a case by case bases most are pretty nice, but if you put them all in the same room together things get sorta 'meh'.
So with that being said I guess I like jerseys that offer something a bit (or a lot) different.
Germany - All three uniforms get a thumbs up from me.
Sweden - The yellow jerseys I really like. Don't mind the blue ones.
Latvia - Not a lot of claret in hockey.
Belarus - Green is seriously lacking in (elite) international hockey. Wish it was at least a bit more prominent on the Belarusian uniform.
Finland & Kazakhstan - They are blue, but at least it is a lighter shade of blue than most. Perhaps more importantly there isn't any red.
I wish places like Lithuania, Netherlands & Romania would suddenly get into hockey and become awesome at it for no other reason than adding a little colour.
these Hungary Jerseys are pretty cool. idk when they're from though. don't think they still use em.
Fun fact: those are supposed to be two-color numbers. Red is the base layer, but there's supposed to be white on top of it. Long story short: the vinyl they used was crap, so the white ended up flaking off a bunch of the game jerseys.
There's also a set like this from the mid-1990s that actually had the Bulgarian flag for a stripe instead of Hungary. Hungary goes red-white-green (from top to bottom), Bulgaria goes red-green-white.
