I'd say it's worth it if you think it is. It's an upgrade from the V30, in my opinion. My husband got the G7 ThinQ in September and loves it! It has had great standby time and he's a power user and it gets him through the day. Plus, I think the camera takes decent shots.
But, again, it's up to you and depends on whether or not you'd like the "newest" phone or previous iterations. If you still can't decide, wait a while. Go to a store and hold your top "phone contenders" in your hand and try to think about which one you could see yourself using/picking up/holding for long-term.
Let us know what you decide!
