Which would you choose?

Magnepa 1.6's is also another one should consider.

The bass driver and the electrostati panels on the sequels do not match up very well and that should be more like 10+ years old (they made those in 1989 when I bought my Magnepan IIIa's)

I agree with Mang53. I would add Innersound Eros to the mix.
If you can find a set of Eros Mk2 or 3 you should give them a try. The new replacement for the Eros called Kaya runs 20k.

If you have the space, I much prefer the Ascent to the Aeon. It is worth the price difference. A used pair of Sequels is certainly the bargain of the Martin Logan group, but it has been too long since I've heard them to make a direct comparison to the other two. I haven't heard anything by Paradigm in a long, long time.

I'd take the Paradigms just because I don't like any of the other options. I'm not an ML fan, never heard one that I liked.

For your size of room I would recommend the Ascent.

If all your upstream components are good full range Planars (Apogee, Maggies) or Electrostats (Quads, Soundlabs) let the music through.
For example play the cd from Sara K listening with the song "Whipping Post" your brain/ear will sense a person is playing the guitar. Low to mid price dynamic speakers portray this same event as if the guitar is machine generated albiet with a bit more dynamics. But the increase dynamics are mechanical not natural.

If only one day we can combine the strengths of Planars/Electro with the strengths of top shelf dynamic/horn speakers!:)
