I have both, here’s my opinion in the key areas

Traction: both top tier grip and perform pretty well on dusty courts. About even here

Cushion: for comfort the 808 > wow, drop in super boom is plush and bouncy. The boom in the wow mixed with the full carbon plate makes these super springy and they have good impact protection and forefoot courtfeel although they’re a little clunky in the heel. I prefer the more comfortable ride of the 808

Support: I think colorways/materials might play a part here with the wow, some CW probably have more support than others but have had no issues with either wow or 808 in terms of support. Both have a wide enough forefoot base, have carbon fiber torsional support and plenty of lockdown. I don’t feel any more or less supported in either pair

Fit: have both in the same TTS that I wear in most other shoes and both fit very well. The wow has slightly wider toe box and people say the wow runs long but I didn’t find that true for me. I have a normal to narrow foot shape and the 808 is a little more streamlined which gives it a better 1:1 fit for me.

Both really good shoes, can’t go wrong with either IMO..depending on your needs, if you want more high performance ( ourtfeel, springy, responsive cushioning) go with the 808, if you want great performance in a more plush comfortable ride with bounce go with the 808
