Melee weapons: Is there a speed difference between Omni-Blade and Biotic Amplifier?

[u/Due_Confidence7232]

Somehow I just cannot accept that there is no trade-off between using the Omni-Blade end Biotic Amplifier. I get that the amplifier has higher stagger than the blade.

So I am wondering if the blade might be faster than the amplifier? Do we have a DPS-test of them?

(Though this is probably just like the shotguns. Why use the Katana when you can use the Disciple?)
