If the money difference isn't huge, go with the three roller mill. You may not care--now--about keeping the husks intact, but you may decide at a later date to pursue other brewing methods that require a coarser crush and the husks to stay intact. You may decide that a slow crush is desirable and a mill that works well at that lower speed would be desirable.
I bought a MM3 at the end of 2017; it is, truly, a monster, and when coupled to an electric motor, it's the nuts. I bought it in part because I want it to be the last mill I ever have to buy.

As I look back over the last 2 1/2 years during which I went from a Northern Brewer kit to my current MM3, two ferm chambers, keezer, Spike CF10 conical, Spike kettle....I look back at the decisions I wish I'd made at the outset.
Knowing what I know now, I'd have never bought that NB kettle, I'd have gone right to the Spike. I wouldn't have bought extra Bigmouth Bubblers--I still have two, siphonless, NIB. And I wouldn't have bought my Barley Crusher, instead putting that money toward the Monster Mill 3.
I know, I know--when we start out we don't know if we're going to like this, so we minimize our expenses so that if we decide to quit, our out-of-pocket cost is as small as possible.
But I sure wish I could go back in time and undo some of those earlier purchases.
The point, which I'm sure you've got, is to think about what you're going to wish you'd done a year, two years, three years from now. Rarely do I regret buying as high a quality as I can afford.
Think really hard about what your best long term purchase is going to be.
Good luck!
