Pretty sure anyone in their right mind will tell you be patient, save your money and go with something quality.
RC is the temu of the lift/level/suspension world. Does it work and get you by? Yes it will and it does. Will it last long and will it be the same quality as a brand name or a "designer" name? Not even close. Anyone who has had RC and left to go to a quality suspension usually never go back for a reason. Only people getting upset at comments like these is because its what they run, couldn't afford better or patient enough to save a little more, and dont know any better of a quality system. RC will work yes, but are you will to spend that money and gamble a 50/50 shot to ruin your expensive nice truck causing more damage on top of having to re do it after its all fixed and spend even more for something you should have done the first time? Not worth it to me. OF COURSE there is going to be people that say "well i ran it and it was just fine"... that doesnt account for the other half and thousands of others that had issues and or caused more damage to their truck, and "A lot" of the time... gona get some hate for this but owell.... people who say it was fine usually arnt doing anything with there truck except driving to their office job and not towing/hauling anything anyways.
As for your designer term think of it like Rough County is Walmart, Bilstein and Fox is brand name, Carli and King is the designer.
Is it really that hard to save an extra 200-300$ to go from say RC to Bilstein or Fox for a set of shocks? Your driving a HD truck that cost 10s of thousands of dollars, to me thats crazy not to just wait and go that route. At that point your ego is in the way because "oh i have to have a big bad lifted truck right now".
Dont think its "everything else for peoples preference is trash".... i think when you compare quality suspensions your comparing everyone's biased opinion say between Bilstein or Fox and Carli or King. Its apples to apples between the groups. But im sure anyone running the 2 groups can agree.... RC isnt even in the conversation between them and all know... They arnt good, they "just work". Thats it.
Anyways, what im saying is just..... be patient, save a little more and get something more reliable and better.
