.... and by now I'm having a hard time understanding how coat A is better than coat B :suspicious:anyone care to educate me

Maybe a part 2 of the Teflon coating will also come back?
Yes, there's a lot of new tag alongs, most of which are either inexperienced in the field or have found some "walmart" of coatings to churn out and relabel older tech without investing in any evolution of the technology. Of course their may also be some innovation buried among them.
A few of the variations you will likely find.
The sliding angle and contact angle will often vary
Some coatings peel off or chip
Some coatings are better than others with chemical resistance
Some last longer
Some yellow
Some are softer than the surface they were applied to
Some are difficult to apply
Some offer better scratch resistance
Some offer better heat resistance
Some are simply sealants
Some are full of it and like using fancy words
CarPro and Optimum are the two lines I have seen with proven coatings and multiple reviews and feedback. I tested them both side by side back when they came out. Both of them lasted up until I decided to polish the paint at which they were both removed of course. On another vehicle I tested them on both are still there to this day (more than two years later) however both sides of the vehicle don't look like they did in the beginning. Vehicle outside 24/7
There's 3 customers vehicles that I still see that CQ was applied to nearly two years ago and and a few between then and now. All of which are still beading and sheeting water very well.
A buddy of mine also has had CQ on his work truck over two years and tells me people still comment on it to this day. Because I speak with CarPro customers daily I hear a lot of feedback of these same stories from others as well.
As far as being permanent there is no such thing on this planet. Even clearcoat and paint is not permanent as we have all seen it eventually oxidize or peel off the vehicle if kept around long enough.
The most important step in any coating is the entire prep job from decon, to polish, to removal of all oils from the surface without replacing it with some byproduct of whatever cleaner your using.
An important thing to keep in mind is most customers that care enough to apply a coating will also polish their vehicle again within a couple years. At this time the coating will be removed.
A lot of people are just happy with seeing a car bead for as long as possible but coatings do things that are actually important for the paint. CQuartz, UK, and Finest, have been tested independently multiple times on many levels all the way up to scratch resistance which is improved beyond the original paint surface it was applied to. CQuartz really excels at how well it blocks rail dust, brake dust, industrial contamination, etc, from adhering to the paint. It literally blocks this stuff from getting to the paint and semi annual iron x treatments easily remove the iron without claying.
When you first prep the car you should clay also as there will be some things IX doesn't remove however after CQ is applied you'll be shocked how pointless clay becomes and how easily proper care removes the contaminants from the coating.
