I don’t have experience with a complete bed kit, but as far as bedsides I have purchased 2 sets since 2016.
The AMD/key parts/tri plus bedsides purchased in 2016 were for a long bed.
They fit good with the original sheet metal front panel, wheel tubs, and steel floor. They were a bit wavy but not bad. The reverse lights and taillights were tight but I was able to make them fit. The 1 thing that bothered me was that the inside of the bed and stake pocket area was not spot welded like the original.

The next set was shortbed sides from Woodall purchased in 2020. They are much straighter, fit was good, and the inside of the bedside and stake pockets are spot welded like the original. Again the reverse lights and tail lights were tight .l would buy them again.

Perhaps the AMD sides have improved.
Just a couple things to consider/look out for.
