for whom or for a what?
See if you know it and cover your needs yes.
If you are a DEV yes, and sell sites yes.
if you run your site alone and you know only Joomla or Drupal NO.
If you now enter the market maybe WIX or other alternative is better depending on your needs, your free time, your prior knowledge and your BUDGET.
It is not so simple, there are a lot of factors.
