KT have 8 displays they sell cheap. Even in china engineers expect pay and need time to develop products fully. You yourself are moving on to something new...

For my use case (old guy with family) my preference is definetely not a (bleeding edge) expensive colour display. My choice would be:
a) Make motor work with standard, unmodified XH18. Motor can be configured by LCD3/pc-file/phone, then nothing else can be changed by standard XH18 - this is perfect for my family to use. This opens a much bigger userbase than any other option, and should only need a small additional code in motor.
I tried to get tsdz2 without XH18 from pswpower, but seems to be bundled. So XH18 is "free" - no cables, no farting about. (LCD3, cables, freight will cost about USD90 extra)
b) KT-LCD5 is preferable for use by my family over LCD3 as it is simpler, less confusing, less wires, smaller-less breakable. (note I am happy with just not seeing the things that are missing from LCD3 display)
c) reprogram XH18: already has correct cable. Small, clean, robust.
I will have one LCD3 so I can see/set everything, and set up bikes for the wife and kids. I would rather have lcd5 or XH18 on their bikes.
Also we have two bike already modified for XH18 - I would rather not change them.
Programmability on-the-fly for my family is a minus: my wife is certain to accidentally get into a menu and change the motor current or otherwise break it.
Kids are certain to set motor current to 125GA deliberately, and burn it out.
Extra display items of LCD3 are only a plus for me, they are just confusing for everyone else.
