+1. I run an Aqua Clear 500 and a Fluval 406 on both of my 90's and they are crystal clear and my levels are right on the money. When I service them I do them a week apart so there's almost no chance of upsetting the apple cart.
Canister vs HOB

You never have to remove the motor to clean HOBs, so there is no O ring to wear out. AC is the only exception in that the manufacture recommends removing the motor to clean the impeller. But you don't have to follow the manufacture instruction and can clean the impeller from inside the box.
Yes, sump systems have external hoses, but no clamps and O ring to wear out. The plumbing for drilled systems is permanent, and never need to be taken apart after initial set up cleanup, so there are no parts to wear out. Sump system is complicated to set up, so it is not for everyone. But once it is set up right, it's a safe system.
Canister is appealing because it appears sophisticated and is relatively easy to set up. But the design is inherently unsafe waiting for accident to occur. Many hobbyists are passionate of their equipment as much as their fish and think I am an alarmist until accident happens..
Flooding and fish death don't impact human health or kill people, so there is no law against it.
O rings are actually quite reliable. They use them on nuclear submarines on many of the systems. As to the clamping arrangements, observation and examination during maintenance can help avoid failure. Or get an fx5/6. Moves the catch system up a notch. Cannisters imo are very good. Im sure there are failures, but if they were that common they would have to cease production due to lack of buyers. If we based all of our lives on each and every 'what if' we wouldn't do very much.
That being said, I do prefer my sump.

When a HOB leaks, it's water puddles. When a canister leaks, it can drain the tank water down to the intake. Canister accidents don't happen often, and if it does, it's mostly human error, like not checking for leak after assembling it.
But my dislike for canister is that it is tedious to clean. But if you are lazy and don't clean it often, toxic gases can build up in the can in power outage which can be dangerous to the fish.

Canister... clean every 3 months
Hob clean every 3 weeks (depending on bio load)
Hob 30 second cleaning
Canister 15-30 minute cleaning
Canister.. in a cabinet quiet
Canister.. not in a cabinet, just as noisy as a hob

I think he was being sarcastic.
That being said, I run sumps, cans and hobs. Never had a leak. Overflowed a few, but never a leak.
Orings are cheap and I replace them every year or so.
