Unfortunately, I don't have a ton of experience in DWC. Hydro yes but running wool blocks rather than full on water only. I do frequent a site that has some real hydro/RDWC experts that can guide you through the entire process from setup to harvest but this site discourages posting links to other grow sites. Probably some of the best, most knowledgeable RDWC guys I've known.
I've run water culture maybe 10 times so I don't really have enough experience to comment on what the best setup would be. When I do RDWC I usually just cobble together a system from disparate suppliers. I will say that most of the all in one systems I've seen are pretty much the same. There really isn't much to an RDWC system other than making sure the water pump is working as it should and there are no leaks.
The first time I ran DWC was with a buddy of mine. He lived in an apartment and wanted to get into growing. He called me up to go with him to the hardware store as I had some experience growing weed. He decided that he wanted to go big so he bought six 30 gal Bruiser trash cans with lids. He also bought some net pots and hydroton. He was going to cut a hole in the top and put the net pot in it along with the hydroton for media. Big air pump and some 8 inch air discs and we were complete. I cautioned him against using such large reservoirs but he wasn't having any of it. While all this was going on I asked him if his wife was going to be OK with him doing this in their apartment. He puffed his chest out and started saying crap about how he was the man of the house and if she didn't like it she could go pound sand, blah, blah, blah.
We get everything setup and running and the wife comes home. The moment she sees what we had setup she fucking lost it!!!
She started screaming "Why are there trash cans full of water in my dining room?!!??"
My buddy tucked tail and hid in the bedroom. I was laughing so hard that she kicked me out of the apartment. After a few days I go over to my buddies apartment to see what happened. Everything was the same but his wife took me aside and told me she was really frustrated with me. I asked her why and she told me that I should know that I'm the adult in my buddy and mines friendship and that I should have told him no!
The difference I see is the GG is turn key while the PA is accessories only and you need to provide the square buckets and hydroton. Kind of apples to oranges. If you have a source for the buckets and are willing to go hunting for all the other little shit you may need to complete your system then go with PA otherwise GG.
Honestly, this system would probably do just as well as the ones you noted at a considerably cheaper price.

I would look for the cheapest way to get my system together to see if I even like that grow style or not. As I mentioned, I've been growing for 30+ years and have grown in practically every different type of system but I keep coming back to dirt.
