Hey there. I've tried both. They're ok. They will do the job, but not much euphoria. The Vanuatu one is sooooooo extremely skunky and in my opinion, the skunk doesn't match up the with the effects. You'd think the skunkier, the harder it is, but that is only sometimes true.
This stuff is noble and safe, just not very good. If you need a cheapie strong kava get the Mood and Mind off of amazon. Their batches vary, but what they have right now is fresh and heavy and has good euphoria levels. Very good for sleep.
