Both. You can get both digital and analog with a 7,2 volt FET wire. The reason they're fast, is they are supplied with 7,2 volt, instead of the 6 or even only 5 volt from the BEC.
If your ESC only got a 5 volt BEC, I would definately get a servo with a FET wire.
If you get a KO servo with a FET wire, the servo comes with a little manual wich describes how to wire it up.
Choosing a servo on a limited budget, can be hard.
I think I would priority like this:
1: A brand with good reputation.
3: Metal gears and double bearings. For precision and longer lasting.
And step untill, I met the budget roof.
