If you read enough threads, you will see a trend. Lots more folks do DWC/RDWC, etc for the exact reasons @LED_Seedz mentioned above. Its the most popular system so more people see it talked about and THINK its the "best". But 0 you will also see that they seem to heve the most issues with root rot, etc.
The aero folks have technical issues - especially the hi pressure and fog-ponics folks. Lots of technical challenges there and it gets more and more finicky as you go higher tech.
Ebb/Flow - Flood/Drain in all its variations, fall in the middle between DWC and aero and those folks seem to have the fewest issues from my reading. Well, the exception would be hempy buckets or similar systems. Those really are the least trouble and simplest and most reliable hydro systems.
I know they are not sexy - thats the ONLY reason Im not doing hempy Well, actually I am doing hemy with two "extra" clones I had from my first hydro grow. I stuck two clones in small plastic buckets filled with perlite and stuck them in my bath tub and forgot about them. I water them when ever they get super droopy and they get very very little light - 14 watts screw in led on 24 hrs a day. The stupid things look GREAT and are bushy as heck. They are barely growing, which is exactly what I want for now. Im going to use them as mothers while I learn how to clone.
Point is - nothing is as simple or easy or reliable as hempy. Its just not sexy
As far as nutes getting "left behind" that would tell me the nutes were not dissolving properly and were not suited for hydro use. That issue would apply to DWC or any other hydro setup just as much as Ebb/Flow. If you use crappy nutes, that dont dissolve, you will get crappy results.
There are a number of NFT setups that might be suitable for a beginner, but I think Ebb/Flow would be a better place to start than DWC for a newbie if you cant stand the thought of doing hempy
