Old question. Like @ChrisVic said, both are the same now. FastCli was a faster version of the Cli tool. In the pre 4.16. X EOS versions, If you ran a show version command using the Cli tool it was up to 20x slower than using the FastCli tool. However, in more recent EOS versions the FastCli and Cli tools are exactly the same

FastCli is considerably faster since it does not spawn an entire Cli session to execute the command
