Ah, not quite: WikiFeatures switches the default editor for logged in users (for those who have their preference set to 'Default'). You can still use the VisualEditor on a wikia where it has not yet been set as the default.

As a rough pros/cons: if you mostly edit via wikitext, the VE probably isn't for you. The old and new visual editors have slightly different feature sets (especially as the VE is still in heavy development). I suggest trying it out to get a better feel for it - you can always switch back.
