I have used auto links for tint, they also use the formula one line, if I remember correctly the advantages of ceramic are
Highest heat and uv rejection (so you don’t have to go as dark)
Doesn’t interfere with cell or gps signal
Colour never changes over time

The next one down was a metallized film which could cause gps interference but with the advantage of being colour stable unlike a dyed film.

I’ve got it done in 3 cars now and always went ceramic for the heat/uv
