I recorded a short video about the recycle time on the Pixel X900C and compared it to other Speedlights like the Shanny SN600SC and Yongnuo YN-560. The Shanny is the fastest Speedlite I own at the moment and I like it very much for Event Photography where the recycle speed is important to get a lot of shots done. But as an advantage, the X900C has lithium batteries, so it should be even faster. Unfortunately I don't own a Godox lithium flash, that would be a fair comparison. ;-) On the other hand, the Godox speedlites don't have a LED videolight built in.
So that should make Pixel the fastest in its own league ... with LED videolight kept on all the time. ;-)
