Best UX for leaving a product review?

We're re-thinking our leave-a-review flow (you all are leaving lots of reviews, including founder reviews!) and I wonder if anyone has review flows they think are 1) easy to use, and 2) actually help you write better reviews. I'm looking at G2, Trustpilot, Yelp, Google...nothing's standing out as amazing.

Would love any UX inspiration here! (or ideas/requests!)
