Is there an advantage to Featurizing a view, over using Views' export?
For a single View, there is no difference in functionality really. The view will be the same regardless.

I use Features anyway because it's makes it more conventient to organize multiple pieces of configuration into "features". I'm not aware that ctools offers any easy way of doing "This view with that panel and those three dependencies in one module". That is what features adds on top of Ctools.

It's worth mentioning that the Configuration module is an useful alternative that largely makes the configuration tracking easier. If you don't care about the features aspect of features, take it for a spin. (Thanks Clive for pointing this out)
