How good is dom perignon 1998 vintage?

In my opinion it is very very good. I have tried the 98 and 99 and whilst the 99 did not do a great deal for me the 98 blew my socks off. the 2000 is the latest vintage but I have not tried it yet. £100 for a bottle of wine seems crazy but if that sort of spend can be justified then the Dom 98 makes a pretty good case.
