VS is much better today but it's still a 32-bit process that's limited to < 4GB of addressable memory. Jetbrains has been on a multiyear journey (documented with fantastic blog posts) to move Resharper out-of-process but there's still overhead in maintaining separate systems working on the same project space.
Rider bypasses all of the process limitations and syncing overhead by using the Resharper/C# logic exclusively, and is much faster and more responsive as a result.
Also VS has been slowly copying Resharper features but is still far behind. I mostly use VS today for heavy debugging where it still excels.
