What we want to you know as backers is your personal preference based on your time with both ! But also the reasoning and though processes you go through to make your decision. (assuming you use controlled testing)
Having tried both, you are in a position to do a functional side by side comparison of the two models whilst also being able to directly control the configurational setup to a control based standard. This is a position that is not available to the majority of us..
We don't need information about 'how to use it'. Most of us would already know or can figure that out.
We are interested in the quality, performance, sde, distortion, latency and affects whilst playing games or using virtual environments such as bigscreen..
If your goal is just to say here are the 5k+ and 8k and that they are similar then that is not good enough from a critical lens viewpoint.
As an 8k backer I would want to know whether whether the $100+ (could be more at retail) price difference is justifiable between the two from a performance and visual quality perspective. How are we supposed to know if if we are to downgrade if we cannot even have a chance to try it.
Your opinion is important for us as it is one of the few voices that can help us make the decision based on our setup and needs. Yes give us facts, but also give us your personal opinion and your reasoning based on testing and methodology, because that is the true purpose of a review. Weigh up with well weighted opinions based on the testing, otherwise, it is not a review, it is just a video demonstration after which we as backers might end up still frustrated and confused after watching.
As an example, your berlin videos were much appreciated, but due to the environment, high subjectivity and lack of a proper test control environment, that just provided us with a lot of subjective confusion.
Also please factor in whether a 2080 Ti in future might swing the opinion
