Enduro owner here does it all, haven't looked back. Recently went through OP's dilemma.
I did try the sb66 - very good quick bike, but sizing a bit long. Tried a nomad didn't like the riding position.
Didn't try the mojo HD, love the look but I discounted for the geometry being a bit dated so thought something new may be around the corner. Then the HDR came out and really don't get that.
Sat on the enduro and it just felt right.
650b is growing rapidly so you may want to go that way to future proof the investment. Spicy or Bronson would be my pick of them. But for me it's a 26er for the next few years
