Well the fight was a lot better with how Juvia vs Meredy went down.

Well for Natsu vs Jackal, in my belief Jackal would have won when Natsu became a bomb and went down, the only reason it didn't was because of Wendy healing him.

If Natsu really is E.N.D. That would explain why he wins in almost every fight.
