Essie all the way, its only 1 power off Eyrton and has the ability to become a 10...enough said

Frankly I'm not too fond of either, they're both bulky and don't have damage worthy of a 5*. Especially if you're going for a T1/ELO deck, I'd consider doing some star rearranging and putting some of AllStar's good 4*s into your deck. Marina and/or Striker if you have lots of money; Loma Noju/Alexei/Asporov if you don't.

If you're doing T2, get both. T2 decks are easy; just cram your deck with all of the 5/4*s you like best from a clan. Profit.
