I think for the majority of triathletes sub 6:00 is a dream that will not ever be attained. More like 6:20 and 6:45/:50 for M/W to be off or near the very front of the AG swim in the majority of races anyone will do. (local/regional/70.3/IM)
I have data for about 120 adult onset swimmers, we do time trials regularly. There are exactly two who started competitive swimming after 30 and have a 500 time trial under 7:00.
The OP didn't say his age, so I am making a big assumption.
To the original question, what is good; without a frame of reference there's no way to say.
But you are right in that a person who swims 6:20 is right near the very front of a regional race. Though there is usually that one former division 1 swimmer well off the front.
