Nike also has ZoomX for their cushioning on VaporFly. Rumor it would also be available on the upcoming Pegasus Turbo.
At the end of the day, it is really depending on yourself which cushioning that you feel comfortable the most. In my case, Lunarlon works out the best for me, not too firm not too bouncy yet still offer stability.
Zoom Air is about the same as Lunarlon eventhough they are firmer. The full length zoom air like on basketball shoes, feels much better.
IMO, boost is too bouncy, especially on the EQT 93/17. I watched the review on BYW and they all said it is very bouncy.
I'm patiently waiting to try on React. Based on all the reviews so far, they are very promising. I would watch the review from Kusto. His review is much better than others.
