Hempy or Coco DTW?

I know they are very similar but what do you prefer? If you've ran both let me know what you think the pros and cons are of each, or how they worked out for you. Anyone ever use coco DTW then hempy or vise versa and really prefered one to the other?

If I do Hempy buckets they will be a perlite/coco mix probably like 3:1 or 4:1

If I do coco DTW they will be the other way around coco/perlite 2:1 or 3:1

I'm using GH FloraNova Simple DTW nute line(and a couple other things):

Grow
Bloom
Floraliscious Plus
Liquid Cool Bloom
Atami B'Cuzz Roots
Great White

Any input would be great!

OK I have one more medium to consider: PROMIX (Just like the coco DTW)
