Turning on circular logging limits your restore options immensely. I've had numerous situations where a server has failed (usually a power surge that has blown the UPS and the server) leaving the Exchange database corrupt. With all the logs since the last backup in place (because circular logging is disabled) you simply restore the database. Exchange then starts up, notices all the logs are still there and brings everything up to date. It's a no-loss recovery. No mucking around with eseutil, no fretting over the weekends worth of email you might have missed, it's all just there. The 'restore to a point in time' was a useful thing in the past but it's not the reason you would want circular logging disabled - retention policies take care of recovering accidental deletions etc these days.
