Wow, thanks for sharing you insight and measurements! I am tempted to go for the 18WU instead of the other suggestions.
Yes, the MW16TX measures better and has a larger usable frequency range as mid.
As Pida says: It depends how it will be used,
like he implemented it in a 2-way the ScanSpeak can be great, but as mid in 3-way there are better options.
There are THD and IMD measurements of both, although from different sources:
18wu4741t00
purifi_ptt65w04
satori-mw16tx-4

Take a look on this project:
HC-GigaLCR DIY kit by StereoArt
Drivers are inexpensive, but good and matching:
1 x SB Acoustics TW29RN - 109€
2 x SB Acoustics SB15NRXC30-8 - 41€
2 x SB Acoustics SB23MFCL45-8 - 105€
Crossover is well designed - excellent off-axis and phase response, top components - Mundorf MCap EVO Oil, Baked AirCore coils.
It goes down to true 30Hz, soundstage is wide and deep.
Full kit include all what you need to build - wires, terminals, damping, solder, drivers&components (all except cabinets) - 1775,00€ with free shipping
In future you may upgrade tweeter with SB Acoustics Beryllium Satori TW29BN, but it will require to adjust crossover.
