Just wanted to add that the answer to OP's question, as always, depends on a number of variables.
There are certain things that the KVS Tool can do, but the other service can't (e.g. show availability for CO award/upgrade booking classes). On the other hand, if one needs, say, AA award/upgrade availability, the situation reverses.
