I've found it's pretty good in tight quarters, particularly when your allies are between you and the enemy (thus providing cover to the enemies) such as in a choke point battle. Being a Con save and poison damage means it's not ideal on some enemies.
Truthfully though, most games are not hard enough in my experience to always need to take the most optimal options. So if this fits some kind of theme you have in mind or just sounds like fun, go for it. Just know its limitations.
