User blog comment:Leolab/Elemental Archfiends (FFIV) vs Four Fiends (FFI)/@comment-422690-20110828134510

I'm going Elemental Archfiends here. Even though I haven't fought the Four Fiends (I have yet to get FF 20th anniversary edition), the Elemental Archfiends I've fought (all except Rubicante, and on the DS port) have been some of the hardest boss fights I have ever seen. They are extremely powerful with some obscene full-party damage abilities. Scarmiglione's and Cagnazzo's status effects will continuously hurt the Fiends, and Barbariccia's Tornado attack can reduce one opponent to 1 hp. Add that to the fact that they get massive defense boosts before their strongest attacks, and you've got a win.
