Well, only with one significant caveat: notation should be generally recognized as well-defined. This way  we would have somewhere about such leaderboard for the wiki:

1.Emlightened

2.LittlePeng9

3.Hyp cos (may be I missed some user of the wiki who invented a strong uncomputable googological function, but among inventors of computable functions, I think, Hyp cos with his strong array notation is the first in the wiki)

...

and so on.
