Both have good bonus and great cards among thier ranks so it is a matter of opinion
You can't compare them Leaders don't work with each other they work alone. Montan should be compare to Uppers
is good but lack high power cards compare to Uppers
vs Pussycat --> I thinks it is better to compare Junkz
are good for beginners because they have cheap and effiecient cards in the market but thier best non-collector cards are not able to stand against the best cards of other clan in my opinion well maybe with the exception of Copper..
has better damage but thier good cards have high stars.
has better power but thier high level cards are bad.
For now both clan needs some help ASAP.
No Contest Saks closes comparison would be Uppers
or Pussycat in terms of defense.
vs Ulu Watu
have low power but high damage.
has high power but low damage.
If the current meta has lots of damage reducer go for Bangers
if not go for Ulu Watu
FangPi and Junta
FangPi is for One-Hit Ko and the Soleil cards that they have are awesome
Junta is average for both ELO
and Daily Tournament if you know how to use them properly
