I would rank Cana as A class (with an weak argument for B class).

I say this for the simple fact that Cana was chosen by Makarov to take the S class challenge multiple times as he believed she had the potential to be in the S class rank.

Cana is a side character, we don't get to see 150+ episodes of the quests she's been on to keep up a very extensive drinking habbit (Natsu struggled financially while he was a B-C rank and without the drinking habit).

Cana is also well respected by all the members of the guild and is seen as one of the main guild members.

The argument for B class The real strength of the guild and it's members lies within the friendships and trust, unfortunately Cana is a loner who worse still has little faith in herself, this failure to trust her friends and herself is why we see her fail and the others succeed.

Cana's cards are not particularly powerful (compared to lucy's zodiac spirits) however Cana has more variety, can customise her cards (she purchases them) and they can be deployed very quickly which would make her a very valuable member to have on a team.

Cana is not overrated in the guild, she is just underplayed in the show.
