Normally I compare the latest public builds against the newest public / beta builds. This can help iOS users to decide if a new release is good enough performance wise to make them want to upgrade.
And for the Beta versions, to see what is in store for the next release as it is being developed.
Many have suggested that I would do a beta vs beta video, and this is the first go towards such a video. I will keep one device on iOS 11 Beta 1, and then compare that to the newest beta. Hopefully it will be clear
