Please re-read my last post, it answers this post already:Sorry for the inconvenience: I actually thought Salamence and Volcarona both where A+ so thats why I compared them that much.
You guys are right that certain Z-moves/Hidden Powers enable Volcarona to beat certain checks. However, you are all a bit implying as if the Z-moves enable Volcarona to beat ALL of its checks at the same time. If you say Garchomp is the only real Volcarona check, then I think you are forgetting that if Volcarona wants to check Salamence (with Hidden Power Ice) it can't check Heatran anymore (Hidden Power Ground) and vice versa. This goes up for a lot of its checks and not just when it comes down to Hidden Powers: with Z-crystals Volcarona must choose to win versus some of its checks at the cost of losing to other checks.
Volcarona only can run 4 moves and one wouldn't disagree slot 1 and 2 are meant for Quiver Dance and a fire type move (such as Fire Blast). This means Volcarona has only 2 moveslots to cover the offensive weaknesses it has. You can't run Bug Buzz, Giga Drain, Hurricane, Hidden Power Ice and Hidden Power Ground at the same time and neither can you run a Firium-, Buginium-, Grassium- and Flyinium-Z at the same time, leaving Volcarona be checked by a lot Pokémon still.
I think Volcarona lacks a lot bulk prior to setting up too, whereas the Charizards also have defensive utility, as well as more immediate power (thanks to their very useful abilities).
Yes, Volcarona gets hard-walled by some Pokemon depending on what moves / items you choose to use on it, but none of its checks can actually safely switch in on it due to the threat of being hit by the correct coverage move. No one implied that Volcarona is capable of beating all its checks at the same time, you inferring that is an error on your part.It's also arguably the best Z move user and can essentially choose what it loses to which makes building around it very easy.
