What I like best about G2 reviews is that they have you prove that you actually use the software with screenshots. That way you know the people reviewing it are authentic. The review process takes a bit of time as they are thorough with the process so anyone reviewing has to take some time unlike typical reviews with a one-liner that you're unsure if you can trust or not. The only downside was a lot of scale-rated questions that often don't apply to the user doing the review.
