From what I’ve been able to read, people who bought the v1 aren’t looking to get a v3 usually.
I haven’t really looked at all the specs, because should I get one, it’ll be the current iteration anyway. However, iteration is usually made because it’s worth it. So my guess is, if the differences between the 2 are important to you, then just get the v3.
