The decision to limit the class to three boats was made before the first hull even hit the water (some suggest the reason
Connecticut "broke class" and went with a state name was that during the 1992 election Bill Clinton managed to secure the state's votes by promising to continue production of the class past
Seawolf; at the time between the "Peace Dividend" and the initial overruns it was looking like it would be a one-off). The original plan in 1989 was to order 12 boats at a total cost of $33.6 billion in FY89 dollars; suffice to say that like the B-2 Spirit (over 130 aircraft originally planned, 21 built) and F-22 Raptor (~750 aircraft originally planned, 187 built) the Berlin Wall fell on it.
Seawolf had a lot of hiccups during her 7-year build period which ran up the cost; among other things moving from HY80 steel in the earlier SSN classes to HY100 on
Seawolf proved to be a pain. That said, part of the process of fixing the issues was developing a lot of the production techniques that would be used on the
Virginia-class and made them (relatively) economical to produce. By every account I've seen the three subs in the class are considered the fleet's most capable boats.

The Navy’s future attack submarine will be more like the Seawolf class than the Virginia class, but it won’t come cheap.

I have no current insight into modern sub ops aside from public sources and friends of friends, but from what I gather the
Virginia-class is as quiet as the
Seawolf-class and probably has similarly capable (or possibly better in certain environments) sonar, but is not a match in speed, payload, or diving depth. The USN in the 1990s was really casting around trying to justify itself; the Soviet Navy had just fallen apart, the PLAN was still in a fairly primitive state, and it seemed like the only way they were going to get procurement dollars was going to be focusing on shallow-water and land attack operations against Third World opposition. The
Zumwalt-class and Littoral Combat Ships were born out of the same period, except as surface ships they were built with even less mind to open-ocean fights against a peer adversary.
