Ball valves all the way.
Someone pointed out that they can be tricky to adjust flow, which is
true if you don't practice a bit. It helps to take an uninstalled
one and while looking through the ends, manipulate the handle to
figure out the "crank angle/flow rate curve" in your mind.
One thing that's annoying is the long handles can be nudged and then
the flow starts. I replaced many of the handles with shorter handles
that are 'balanced' across the pivot point of the valve. I can't
think of the names but you turn them with the thumb & forefinger in a
winding motion (like an oven timer).
