Herby vs Durso

[Madreefer]

I'm confused as i've never seen a herby drain in action and have only ran a durso. It has never let me down and I really dont like changing something that is'nt broken. Is it strictly a noise thing? My sump is in the basement so I dont hear anything anyways. Im thinking if I still stay with the herby which is my plan for my new tank I will need to have 6 holes drilled. I dont want to have my returns run up the back and over the top since it will be eurobraced. If I go durso I only need 4 holes drilled. I'd appreciate some feedback on this please and thank you.
