Do SDETs code or just test?

Both. Lead SDET may manage test automation framework, add features, fix problems, review code, while regular SDET writes the data and test cases the framework runs. They also analyze the results and write the defects and update the tests.

Which is more difficult, SDET or SDE?

It’s being an SDET most of the time. You need to know your Application Under Test, JSON, ReGEx, CSS and Xpath, multiple programming languages, SQL, Docker, Jenkins, Clojure, Vue, React, Angular, API, Agile from Waterfall, Git, keygen, and how to write configuration documentation.
