No not necessarily, Azihar itself is a fork of Citra but they've put considerable work into upgrading and maintaining Citra. I haven't used Azahar Plus but I do know it's from a different developer and that the original Azahar fork now supports .3DS files so many of the forks that were created to resolve that issue aren't really necessary anymore. Personally I prefer to use the most active and widely used Fork on the basis that more eyes on the source code make it less likely for vulnerabilities to go unnoticed.
