RHEL - Why does SSH connection select aes128-ctr cipher over aes256-ctr by default?

Issue

• SSH connections by default appear to be using aes128-ctr when aes256-ctr is more secure.

• RHEL 8 default order of ciphers in /etc/ssh/ssh_config file.

  #   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc
  

• RHEL 7 default order of ciphers in /etc/ssh/ssh_config file.

  #   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc
