I think Evilswarms would be top tier 1 with most tournament wins if released into the TCG Meta. Maybe this is my subjective view since I do not like Elemental Dragons and have not much knowledge of the updated Prophecy deck. However, I can objectively say that Evilswarms have become way better and deserve to be top tier 1 if not the top meta. Ophion locks many decks down with protection of Pandemic and Dress/XYZ Reborn. Bahamut Shark is a great card in a mirror match to take control of your opponent's Ophion and turn tides. To be completely honest, even with Ophions lock Elemental Dragons are overpowered and have ways around Ophion such as Blaster.
Overall: The two archetypes are both competitive and compete well against each other. Neither can be said to be better from my point of view unless stated subjectively.
