DMXzone or ProjectSeven Extension manager?

Has anyone used the ProjectSeven extension manager for installing Webassist extensions? I just downgraded from Dreamweaver CC 2017 to CC 2015 and I need to reinstall everything. Thanks.

Update: I installed ProjectSeven's Extension Manager and it seems to have installed Webassist's MySQLi extension without problem. I like that is has a very simple interface.

I've been using dmxzone's one for the last couple of years without any issue. You just drag and drop the extensions inside it, really simple. I also like its modern interface.

They both seem to work equally well based on the feedback I've seen here. I don't like that the DMXZone one always is running in the background and gives an odd alert "Warning" you when you install an extension made by another company, but I haven't even tried the project7 one, so I can't give an unbiased opinion.

PVII is great but install the extension for all the last two DW versions (2015 and 2017). After, every time you need to uninstall from the specific DW version if you want only one (but I think isn't a big problem).
"DMXzone extension manager" is the most complete and powerful but you could see bg running alerts or others marketing messages.
