Well, the taps numbers are about as meaningful as "use third gear for 35mph" kind of statements.The right answer is - it all depends on what you are trying to do.
The very idea of calling taps "X Ohms" is silly from the very beginning. It gives you the perception that this is correct speaker impedance... and it ain't.
Usually it simply corresponds to the point of maximum power. And in most cases matching speaker impedance to the tap one is simply not the best combination.
Some amps are designed with the Pmax point being lower than the "tap impedance", meaning you are getting better drive at the expense of maximum power. And that is often a good tradeoff.
Without going too deeply into this big subject, I personally always recommend that you try all taps, and see which one produces the result you like most. If your amp is designed well, you will not damage it by doing this.
Generally speaking, when using lower number taps you get more control and drive, with higher - you get more open sound. So often people use this as a built-in room correction tool.
