What's probably is the best graphic designing tool?

[Xtynehappy]

So there are so many graphic designing tools that can be used depending on the given context or through the preferences and needs for the clients.
So in general what do you think can be the best graphic designing tools?

Personally I doubt there is any graphic design tool considered as the best. It is mainly personal taste or preference. For me I would say the best is Photoshop, but there are others who would consider corel draw as the best or adobe illustrator and the likes.
