Their SQ gain is questionable and hardly justify additional hassles to me. So I prefer either to use real amp (Pico, Supermicro) or go unamped.

If I assume 3MOVE as my baseline, then T3D is close but still a little less refine on detail and doesn't do soundstage quite as well; T4 has a more noticeable drop in SQ, with lesser detail and transparent but have a likable warmness when paired with RE0; W1 is a little better than T4, with better detail and wider soundstage, but has a certain coloration of its own and doesn't have as much driving power as T3D. So W1 is closer (but better) than T4. I would consider E7 amp section to be very closer , but a tiny bit lesser than T4. It sounds colder and drier than T4, but has a better treble performance. T4 is more musical and has a better soundstage.
If you like a visual reference, it will probably be like this:
Nano's HO ≤ E5 < E1 << E7 ≤ T4 < W1 << T3D < 3MOVE.
My opinion is, if you have the budget and the will, just go as high as you can be. If you really want a very good performance ultra-portable, T3 will be a good choice. Given that you are coming from 3MOVE, I would think you might not be happy with anything equal or less than T4/W1 kind of performance.

ClieOS have you noticed any flickering with the OLED screen? I read somewhere that the refresh rate can be a problem sometimes on OLED screens and can cause a flickering effect for some people.

I have noticed three tiny flashing black lines forming a fast pattern (repeat every few seconds) on the yellow bar where the USB recharging signal is , and I have to pay very close attention to notice them. I really think it is more of a firmware (graphical UI) glitch than refresh rate issue as I didn't notice any actual flickering on the whole screen.
