Sure in movement. But in attack speed, logically that tail would be faster than his base.
Look at Jack for example. He stayed in Full Zoan mode against Sulong Minks....probably cause his strongest weapon (his trunk)....is at its most strongest and fastest in Full Zoan.
The Trunk in his hybrid would be smaller, weaker and thus slower....due to lack of bigger muscles.
Now Drake's hybrid tail would be slower than his tail in Full Zoan....even if his arm was weaker in Full Zoan than in Hybrid.
Either way when comparing DFs....you need to look more at the animal then just saying Hybrid > Base > Full Zoan.
Another example is Chopper. Where his Full Zoan ( Human form) is faster than his hybrid ( Chibi form).
So use logic with Drake's DF. Im not saying Full Zoan Drake is fast in movement, reaction or combat speed with his mouth. But his tail being full sized, would have all the benefits of a strong, muscular, dynamic whip....which could easily pick up momentum.
But yh...knowing you, you will reply with....brrrr.....Zoan form slow
