Well, here goes a flame war.
I got the SS Perlicks with flow control. Then I learned it takes skill to seat everything so they work right. I don't want to worry about skill. I want the manufacturer to take the skill out of it.
I didn't get great results from the flow controls, but that may have been due to my own inexperience and unwillingness to calculate line lengths when I was already paying for faucets that were supposed to make it unnecessary.
I had some problems with trub locking Perlicks up. The beer has to take a complicated path to get out, so if something gets sucked into your line, it can put an end to your fun until you disassemble the faucet. Kegland claims the complicated path makes the beer more turbulent and releases CO2. I had to apply lube to stuff when reassembling.
I stuck the Nukataps on there (not flow control) and had zero problems from the word "go," at least with the faucets themselves. I got plastic Kegland flow control disconnects, and it all works fine. Kegland says the length of the tubing doesn't matter, but I think that is optimistic. I seem to do a lot better with 6 feet than 3 feet. Also, Kegland says the forward-sealing Nukataps are cleaner. A seal kit for a Nukatap costs $5, and seals for a Perlick cost $16.
My Nukataps have never clogged up or slowed down. I had to clean the Perlicks more than once over the few months they were in the keezer.
It seems a lot of guys are emotionally attached to the old Perlicks, and they make excuses for them, blaming users for all the problems. They will always defend Perlicks and claim mastering the arcane science of line balancing is smarter than plug and play. All I can respond with is my actual experience. The Nukataps went in, the Perlicks went to a box in the garage, and the beer has been flowing ever since. If I don't have to become a pro line balancer, doesn't that mean the product is superior?
I could go back to a car with a distributor and adjust it and change the points from time to time, but pushing that dash button and having a modern ignition fire the engine up and operate it perfectly every single time for 300,000 miles seems a lot better.
