The foreign saves are the best ones. I'll often "scout" a save before I start. I'll set up a game with 7 or 8 different leagues open that I may consider and just browse the teams until I see what I like. If something looks interesting, I'll Google the club as well and see if I can find an affinity. Probably sounds ridiculous to most but I enjoy the game and don't do the same old tired game every year.
My favourites have been Torino, Hammarby, AZ Alkmaar and this year's epic Vasas.
The Dutch League is one of the better ones. Next season I think I'll look for a Belgian save because I've never played in that league.
I don't find the rules too challenging for Europe, the worst you get is a Scottish style split for the European places or a limit on foreign players.
The americas is where the leagues are a lot more random. That being said, Mexico might be a save on the agenda for me next edition as well.
These are always my favourite saves too. Had some absolute crackers over the years with the following:
Athletic Bilbao
Gimnastic Tarragona
Cavese
Borussia Monchengladbach
Wehen Wiesbaden
Dynamo Dresden
