Pros and cons of using the old IOS commands
US old guys will use the command wr ter to view the running config
The kids use sh ru
Conclusion: show run is the better command to use, at present you only need to type five characters + CR whereas write terminal requires six characters + CR. Of course some IOS versions allow you to use wr te, which would might make this debate a tie.
However, the show run command allows cool options with the more command, so I'll have to go with show run as the winner.

Us old guys also tend to use wr mem to save a config to the startup-config.
The kids use copy run star
Conclusion:
Hands down, us old guys win this one as copy run star will hurt your little fingertips with all that typing.

Merry Christmas and Happy New Year!
