Here's my advice having no memory of playing AFMR. Seriously.
AFMR is well loved and often compared to MM. I have a TWD LE and an MMR; I love both of them (and they each have their strengths). So, I definitely want to add an AFMR to my collection at some point, and expect it to be a great game like MMR has been to me.
Deciding between the two, TWD LE/Prem is my favorite at this time. And here's the high-level why. TWD LE/Prem for me is a more challenging game, plus there is more code depth and epic coding. It ends up more fun to play (I play it more often) and there are more modes to explore, each with great depth and variety as well. MMR (and I'd expect AFMR) as an overall package is great (super great), but it's more repetitive in the play style and not as deep. MMR is also a longer playing game for me and I prefer the shorter game times and more challenging nature of TWD. TWD made me a better player, which was cool, and all my other games aren't as difficult now.
IMO, both TWD and AFMR are great pins, each with particular strengths. I'd love to have both in my collection, each for different reasons as well as for the variety they have between each other. I've explained what my preferences are and how that led to my choice, so you can compare to what you prefer and want. I happily acknowledge that personal preferences can often be different.
