Without a doubt, the SN10 when introduced was the best at wind. Believe Dave would like to produce something more modern, but Ilec is no longer interested in building varios.

Probably paid too much attention to the panel today, watching winds.
After a change in wind eventually the two varios agree, but the change is displayed immediately on the Air-Glide. Sometimes it was several minutes before the CN caught up.

I have installed and configured but no flight time with the LX90x0/V8 system a few in this thread have asked about.

Looking at flight logs in SeeYou PC isn't the determining factor of which wind is accurate. When SeeYou PC shows 7Kts and a thermal's 360 degree turns don't overlap at all, it's time to say "********". At that point Air indicated 23Kts, way more believable.
