Hi,
I played both for several months. MK on FH, FX-D on BH.
MK is medium-hard rubber with a very good grip. It's not tacky at all, it's classified as hybrid because of lower bounciness then most tensor rubbers. Which is why I liked it a lot. Though probably not what you are looking for.
FX-D is also grippy, but is very bouncy and dynamic. Hardness is between medium-soft and medium. Probably much closer to your Andro rubber. I liked it on practice, but not during match play, cause I overshoot too many serve returns.
Finally, if you're looking for a very grippy rubber in medium-soft/medium range you could have a look at Donic Bluegrip S2. It's the rubber I use on my BH after FX-D. I love it, I've played it for around 6 months now and I'm done with EJing on BH. At least for a while

It's semi-tacky and less bouncy then FX-D. Tackiness makes it the easiest rubber for looping backspin balls from those that I tried so far.
