What I did was install a tee fitting inline to the 1/2" (rigid) pipe under the sink, with a ball valve + a male garden hose fitting coming off of it.
All I have to do is hook up the hose to it under the sink and then open up the ball valve. And because it's on the 1/2" pipe rather than after the point where it changes to the 3/8" (ductile) pipe (or the faucet itself which is fed by the 3/8" pipe), it provides a significantly higher flow rate than any faucet adapter could ever provide.
Because of the VASTLY superior flow rate (allowing for much faster cooling and quicker pot-filling), the ease of installation, and the convenience of having a permanent valve/garden hose disconnect under the sink (rather than having to change faucet adapters/aerators all the time or bring water from an outdoor spigot), I would recommend this to anyone in a heartbeat. And a lot of the higher-end kitchen faucets don't have the threads for a removable aerator, making this solution even more flexible for ANYONE to use.
