Feedback:
omg, omg, plate solving, omg.
Ah, got that out of my system. Installing Indilib was simple enough and had no issues. Creating profile was straight forward. Connecting to az-eq6-gt using eqmod driver and Zwo asi1600 using Zwo drivers just worked.
Here things got a little more difficult, it isn't exactly clear what you need to set versus what can be left alone. It took a while to work past some error messages imply because it isn't clear in the UI what boxes you need to fill in. Documentation on Indilib isn't great (it's mainly a glossary with a few parts on actually how to do stuff). Forums are helpful and devs are active on there, which is great.
Simplest way to get working is to following this video, which I found far more helpful.
One I understood the setup and workflows, Ekos is very simple and easy to use. Last night I was on m33 and m31 very quickly and plate solving -> slew to target works very well to get DSOs centered in your view. Configuring photo sequences is very easy and straight forward, sadly sky conditions weren't great (high level cloud) so I didn't have much to show. Getting focus manually on the CCD was fine using the tools
Issues I had:
Initial config wasn't always clear (text input boxes are exactly the same as current setting boxes, for example, so it's not necessarily clear when/where you need to add data) and it isn't clear what you need to add to get going versus advanced config that isn't necessarily required to make it work
During last session, plate solving stopped working. Not sure what the problem is yet.
FITS viewer not coming to front on occasions
Stuff I haven't done yet:
Guiding
Filter wheel
Polar alignment process
Overall, I am very happy with Indilib/Ekos. Once configured it is very easy to use and stable (ran for over 5 hours over two nights on the laptop on battery) with tracking and photo sequences running without a single failure/crash, missed shot, or tracking issue.
