I have no real preference which one to keep, I will be fine with any decision.
Kata 1. has more languages, and potentially lower cost to move missing languages.
I like kata 2. a bit more because it's older, has more completions, and I think a more accurate rank.

If there will be no clear conclusion which one to keep, I think I will just flip a coin :)

I vote to keep 2 due to higher completion and appropriate ranks plus 1 might be potentially facing copyright issues ~~

Keep 2, older, more completions, etc. and as ejini said as well, I think 1 is from a site that doesn't like their stuff being put on CW.

Keep 2, cooler.

Retire 1 because its description is copied from Codesignal. Moreover kata 2 has more languages (5 + 1 pending COBOL translation; I updated the original comment where available languages were swapped).

[akar-0]

Keep 2 only.

vote for retire 1, keep 2
