The 'Herbie' setup works great for me. My tank only has two drilled holes, so the return goes over the rim of the tank. I ran with a standard durso setup for 15 years or so and not only was it noisy, but I also had a hard time keeping the air bubbles in the sump from making a mess. I highly recommend this if your system is capable of it and I wish it hadn't taken me so long to find this fix.
The siphon flow rate does vary a little so it occasionally needs adjustment, but it's worth it. I have a DC return pump, so I used a cheap ball valve and make the adjustments with the pump. If you have an AC pump, I'd get a good gate valve so you can make the tiny adjustments needed. The regular ball valves are hard to make small adjustments with.
