Hello,
You can find a list of features for each plug-in on the product pages, but I would suggest downloading the free demo of each so you can compare them for yourself. You can achieve similar effect with both plug-ins and the H949 has more features, but the interfaces are quite different, which can lead to a different approach to using the effect. The H910 has a keyboard interface and envelope follower build into the UI.
Both of these are part of the Clockworks Bundle – https://www.eventideaudio.com/plug-ins/clockworks-bundle/
All of the plug-ins that you listed (not including Elevate) are included in the Anthology Bundle – https://www.eventideaudio.com/plug-ins/anthology-xi/
You will not need an internet connection to use the plug-ins once they are activated on your computer.
