Normally I'd vote for annually, since it gives you most bang for your buck, but I'm not sure I'd recommend it with IMVU. Just because they're so absurdly ban-happy and fickle these days, it feels like you're always on a knife edge of getting punished, your account locked, etc.
One thing I will say though, is what is it with companies offering these "exclusive+" offerings these days? I've been spending a lot more time on SL lately and granted, their Premium Plus is
much better than IMVU's higher tiers of VIP like Emerald, but none of them feel truly worth it, unless you're in a particular niche situation like being a
successful creator/shop owner. Not saying they shouldn't have them, but I wish for how much they cost, in this day and age, that it'd be a slightly better deal for what you get out of it.
