After riding them for some time now, I think I can finally summarize them in the following way:
They are not the best at anything, but good in more things than any other truck.
They don't turn like an ace or mini logo, but the turn is very good. (Like Indy)
They aren't super light but light enough, feels great. I don't think I want them any lighter.
The pinch is great (with 54mm wheels) but not like thunder/venture. Basically no wheelbite.
Kingpin clearance might actually be the best of all trucks, I don't know that.
I think the best comparison I can make is: They feel like a lighter indy mid. (I've measured the wheelbase multiple times over the last week and it was always between +3.00 and +3.05.)
The bushings are absolutely amazing, they don't freeze at all.
So if anybody is considering buying indy hollow mids or even titanium mids, just get royals instead. Way more kingpin clearance!
I'm very happy with them and will keep them on, currently on 14.3 wheelbase. Probably even better with a longer wheelbase.
