1Password 8 has a ton of new features and it is faster than the previous version. Some of the new features like Universal Autofill and SSH Agent do not exist in any other product. It also fixes many problems that accumulated in the app over the years.

You guys make a great product otherwise. It’s the only one where I strongly recommend it over the open source alternative (Bitwarden) even though I have a strong open source bias. There’s just a 1000 things in UI and UX that you guys do slightly better than the competition, sort of an inverse death by a thousand cuts.
Also, I certainly understand being the long time Mac expect. However, when we tested 1Password with new customers we found a ton of usability issues and many of these problems are solved in 1Password 8. One example, most new users couldn't even figure out how to create new items right away because of the look and the location of "New Item" button in the old app.
