Who do you think wins?
Personally, I think Fire Lord Ozai wins. He has far more experience than his daughter, can cast overall more fire than Azula, etc.
Her blue fire is important, but it can easily be blocked by another fire bender, shown when Zuko and Azula had a skirmish at the Avatar's hideout after Zuko joined Aang. Azula was casting blue flame, Zuko's flame was normal, but both were blocking the others with their fists.
Also, her flame shouldn't be able to stay blue for very long. When she tried to capture the Avatar early in Season 2 I think, she created a fire barrier, but her blue fire quickly turned normal after a few seconds on the ground.
They should be able to counter each other's lightening.
