Or do we say, they are equal, because neither 2 nor 3 is a probability, so neither of them bounds the probability of the event in any way?

Of course one can argue both ways, but the first (2 is better than 3) would be the correct formal answer since
as a bound, 2 is closer to the actual value than 3. The fact that there is another bound which is better than both, in this case an obvious bound, does not really concern the question being asked
