QDX or QMX+?

Both these QRPlabs products are excellent rigs and I have them both. 

QDX

Most of my operating is either WSPR or FT8 on either 15m or 10m. I cannot recall when I last used SSB on HF because of my poor voice. The QDX is much smaller than the QMX+, but has no display and does not include 6m. Later versions of QMX+ software promise SSB too.

Now, with my limited ability to use SSB, I am questioning if I should keep the QMX+ rig. I probably will for now, but really the QDX would do all I need in the size of a pack of cards.

UPDATE 1806z:   It has been such a long time since I used the QDX that I have forgotten the sequence in which things are connected. There is a known issue with Windows, but not with Linux. For some reason the QDX is not recognised at first.
