Actually, you are missing a delimiter for your output in the 'State'
column for pstat. Dead terminals still appear but this flag changes.

Not very accurate as is, unless you grep the OCc.

[06:54pm]-root@dissent~# pstat -t | grep 'tty[pqrsPQRS]' | wc -l
       8
[06:54pm]-root@dissent~# pstat -t | grep 'tty[pqrsPQRS]' | grep OCc | wc
-l
       5
[06:54pm]-root@dissent~# fstat | awk '{print $8}' | egrep 'tty[pqrsPQRS]'
| sort -u | wc -l
       5
fstat is still the winner.
