Specifically speaking about the USMNT, there is no comparable away game in Europe than what specifically the US face in one of those Central American countries or playing in ground zero hell on earth itself, Mexico City's Azteca Stadium. There simply isn't a comparison, it is perhaps the most advantageous home crowd anywhere.
There are some very bitter rivals throughout the world, Brazil-Argentina, England-Germany, France-Italy, Spain-Portugal - but the one team in CONCACAF which is probably the biggest rival of all the major teams in the region is the US.
To Americans it's Mexico that's the main rival. However, to all the bigger teams of the region, Mexico, El Salvador, Guatemala, Honduras, Jamaica, Costa Rica... etc. ALL of them consider the US their biggest rival (only the El Salvador/Honduras rivalry even approaches it). So the US is facing 5 or 6 teams each time it goes through qualification rounds who are looking back at them as their respective biggest qualifying game. These games are played at a different level of hostility than European qualifiers, some even played in remote jungle stadiums with primitive facilities that host countries purposely pick in order to rattle US teams.
So, someone thinking that American teams have an 'easier path' than the European teams in getting through to a WC aren't taking reality into account.
