Preferences: Shut-offs

This isn't bad, because I can tell that the water is on. Both valve handles are in line with the water path, so both outlets are on. If the handles were crossways the water would be off. I can tell at a glance. Are those screws rusty?
This isn't good, because I can't tell at a glance if the water is on or off. Similar to the connector above, but the valve handle doesn't indicate "in-line" or "crossways".
This is better. Instead of a "valve handle" this shut-off has what the packaging calls a "large easy to use knob". I like it. I know the water is turned on because the knob's grabber is in-line with the water path. Turned 90 degrees -- crossways -- the water would be off.
This one also: I can tell from the position of the knob whether the water is on or off. I find this type much easier to use, this and the one before this, easier to use than the first two shown above. Maybe because the handle is more accessible. Maybe because pressure is applied on both sides of the pivot screw when I open or close the valve. Both those things, I think.
Same story here. Hey... I wonder if the knob would fit on those first two fittings... or on other fittings that give me grief. Hmm...
