between hydranoid and darkus helios who is better

I'd say they're both pretty great bakugan. But they also both have Pros and Cons. Like a couple of Helios' pros are since he's mechanical he can regrow the cyborg parts of him and he can also be given the Maxus Traps. And for Hydranoid's pros he has three heads and as you know "two heads are better than one" (or in this case three heads are better than two) and he can easily destroy his opponents
just by grabbing them and put them again his chest as it spins.
