I'm running the latest raspbian stretch on a Pi2, and it works great, and I've recently added the 7" touchscreen.
So far I'm playing around with nodered and made a dashboard that works great with the touchscreen, however the bundled browser (chromium) seems a little slow.
The people behind nodered recommend using firefox-esr for the editor:

but I already use the editor remotely on a computer with a larger screen.
I was wondering if Firefox is the best choice for the Dashboard based interface also?
I know there is Kweb as well, and I'm not really sure which one to use, ideally I'd like something reliable firstly, and lightweight would be a bonus.
Here's the dashboard node I'm using:
