Squirrly?

Recently got tired of buggy Yoast and switched to All In One. What a relief! It's also noticeably faster.

But I was thinking about trying out Squirrly, as their ads are getting more and more *magnetic* every year. I had their first version installed long ago, and it was unbearable... But it was many generations ago, and they claim serious improvements.

Any firsthand experiences? Thanks!
