I've been using my DIY DWC 5-Gal. bucket systems with great success for years now. I try to keep my systems as simple as possible without adding unnecessary "gadgets" that in no way will benefit my plant/s. My basic DWC systems consist of just your average 5-gal. bucket (dark-colored is highly suggested), a good air stone, air pump, air lines (dark-colored suggested) and those 5-gal. net cup. Yes, of course a DWC system is more time-consuming, more work, and a bit more tricky and all that juicy, good stuff (lol), but if it works great for you and you know what you're doing, and you're not killing your plants with over-watering (especially during seedling stage), overfeeding, over-heating your reservoir, or too much light, then you can get exceptionally-looking plants imho.
Also, if you want "the best quality possible", make sure you don't skimp on the lights you will use on your babies. Lights, imho, are much more important to your growth than any system you decide to use. Good luck on your choice. :smile:
