It really does depend on what type of music you listen to.
Personally, I love MB Quart, Focal, JL Audio, and Arc Audio.
The performance of the speakers is also going to depend heavily on tuning, amp selection, speaker placement and signal quality.
I remember that you're having a set of kick panels made for your truck, so the placement is near perfect. Now, if you don't want to put speakers in the dash (not sure if the truck originally came with them) then I suggest the Focal 165KRC's matched with an Arc Audio amp. Either the KS300.2 or KS300.4 (which can be painted to match your truck), the KS125.2 Mini or KS125.4 Mini (which can be hidden almost anywhere in the truck).
Also, it depends on how much you want to spend. Let me know if you want more information. I can gather part numbers and MSRP on certain products.
