I need some advice to choose an engine for generation web pages from the Spring Boot app. Which technology is the best solution today?

1. JSP + @{JSTL}|tool:2797|
2. @{Apache FreeMarker}|tool:4456|
3. @{Thymeleaf}|tool:2670| Or you can suggest even other perspective tools. I am using Spring Boot, Spring Web, @{Spring Data}|tool:7624|, @{Spring Security}|tool:6656|, @{PostgreSQL}|tool:1028|, @{Apache Tomcat}|tool:1187| in my project. I have already tried to generate pages using jsp, jstl, and it went well. However, I had huge problems via carrying already created static pages, to jsp format, because of syntax. Thanks.
