In our area Leer and ARE are the top quality brands with good dealer networks. ARE's premium caps seem to be the best out there from what I've seen with hardware that is the nicest and best built. I haven't ever bought one, but I looked at them well. I owned several Leer caps, and their top quality caps are not near as nice as the AREs, but their second tier caps seem to be a better value, so that is what I've always bought.
Leer seems to have better color matching than ARE. I've seen many horrible color matches on AREs over the years, especially their metallic and silver/gray caps. My last Leer will probably be my last Leer because I did not love the color match with my brand new truck and the local dealer was unsympathetic and I called and emailed Leer headquarters several times, couldn't get anyone, left messages and never got a call back. So, I'll be looking elsewhere for sure next time. The match isn't that bad, but it is bad enough to bother me, especially given the cost.
If the model you decide on doesn't come with a carpeted inside, order it as an extra, it doesn't cost much extra and is nice.
Frameless windows look awesome (rear and sides), but ask your dealer if they see many broken and ask how much they are to replace vs framed.
. I've always went with models with old style framed windows. Also notice your truck door windows are framed.
Wiring for lights used to be a big deal and nice, but with LED topper lights that run on AAs - they are bright and last a long time, running 12V isn't needed.
