@Dreymar: I play bass, and tried the "cello tuning" on bass, for a while - utterly confusing! Maybe it IS a bad analogy. And yes, Dutch is like a weird German ;-) Like you, I don't know it either what is easier to learn.
By the way, I did find Colemak about as easy to learn as my own mtgap-variant. My own adnw-variant is harder too learn.
I started with this one. Mtgap for Dutch & English.

Very un-qwerty-like. But, not hard to learn because:
- short distances: much used letters are in the best spots; rare letters are further away - this feels logical.
- it has lost of rolls. And I feel that rolls are easy to remember, easy to learn.
But after some time I felt that it was too left-handed, and the rolls started to feel like ' clusters'. Finally I decided to make the switch to Aus Der Neo Welt (adnw). I came up with this good Dutch/English version (* to be filled in later).

This one is better - is found I prefer alternation over rolls. But it is harder to learn. So here is my "theory", I am thinking out loud here.
A new keyboard layout is easier to learn when:
- keys are in logical spots: much used keys close by, rare keys on the harder to reach spots
- one-hand-rolls are easier to remember than patterns over two hands.
- unidirectional motions are easier to remember than to-and-fro motions (like " strat" in Colemak)
- resemblance to Qwerty may be helpful
Colemak, may herefore be one of the easiest to learn. I found MTGAP not hard to learn either, though.
