If you want to know what's on in Herts., then Unicorn is worth getting.

Careful about the session information, though. It's very patchy in Unicorn (for example, the Bushel & Strike, Ashwell is down as weekly when it's the 1st Monday of the month and the White Horse, Hertford isn't in (3rd Sunday afternoons) even though it's been going for 20 years).
