Honestly never got either of the Jasons. I've listened to "Phantoms" and the FSF album with other Jasonn at least 5-10 times each but can't even remember what either voice sounds like
Stephen from Anberlin has always impressed me live too.
I tried to weigh live/studio similarly ... but it was hard with bands I've never seen live, and with artists' I've seen live with zero production value (Acceptance) that killed it vs having a better sound system.
