I have an FX5 on my 125g tank and it is heavily stocked and it keeps up just fine, although its a bit pricey, IMO
my maintenance has never been easier. It's not loud as I too hate the sound HOBs make. There are other more reasonable canisters as well but the FX5 is the only one I have any experience with. I have heard good things about the (Filstar XPL?) but I believe you would need at least 2 of them for a tank that size, but even then it's still cheaper than an FX5. Regardless of the brand, I think canister is going to be your best bet and definitely get some purigen filter media, best decision I ever made.
