 ## FAQ
 
+**How does h2 compare to [solicit] or [rust-http2]?**
+
+The h2 library has implemented more of the details of the HTTP/2.0 specification
+than any other Rust library. It also passes the [h2spec] set of tests. The h2
+library is rapidly approaching "production ready" quality.
+
+Besides the above, Solicit is built on blocking I/O and does not appear to be
+actively maintained.
+
 **Is this an embedded Java SQL database engine?**
 
 [No](http://www.h2database.com).
