XCSkies and Skysight

Up to this point, I've used XCSkies, but I keep hearing more and more about Skysight. I'm trying to determine if I should switch over for the 2020 soaring season. (For U.S. thermal soaring, no ridge/wave.) I've done a trial, but it was only seven days and I didn't really get enough experience with it to determine if I should make the switch.

They both have the HRRR model, but the only other option on Skysight is it's own model which I know nothing about. XCSkies have several models to chose from, of varying vertical/horizontal resolutions.

It also seems to me that Skysight updates the model less frequently the day prior and day of soaring compared to the RAP/HRRR models on XCSkies. That would negate a lot of the benefit of the HRRR model, wouldn't it?

If I'm wrong about any of these assumptions, please educate me. I'm still a neophyte when it comes to using weather products for soaring.

Can someone with knowledge on the models and these websites' methods for employing them describe which is more powerful in predicting actual soaring conditions?

What makes Skysight worth the cost, being twice as expensive as XCSkies?
