Thats a great point. It can be as complex or simple as you want it to be. My 90g/40b african cichlid tank was massively over engineered. The next project is a 125/75g Oscar tank.. I'm going to keep it simple.When talking canisters v sumps don't forget the time investment aspect. With a canister you do a little bit of research on which is best or best for your needs, you buy it and you put it together. With a sump you need to learn to make a complex canister filter basically in addition to all of those steps. There's a lot more time invested to do a proper sump from R&D to implementation to maintaining. To some this is the enjoyable part of the hobby while others may see it as a tremendous drain on their personal time. Something else to take into consideration when weighing the two.
Realistically you can just use tubing instead of hardplumbing if your ok with lower flow rates. Get some filter socks, get some bags of media, forget the lid on the sump. Forget the baffles. Call it a day
