We have similar lists. Honestly, as far as reputation and things on paper, any of those would be a good option. K&S while not a big player has a very solid group (they are mentioned by other firms in the good IP lit firms in the town discussion).
Ropes, Kenyon and maybe Fish and maybe K&S have better "quality of life" reps than Kirkland and Weil. Kirland and Weil have a higher rankings on Vault (if that matters to you), and maybe better bonuses but who knows.
However, I think I would base your decision more on where you "felt" better and where you liked the people the best. All of those firms are great places to be so I think you are almost in a "can't make a wrong choice" position if you liked them all the best.
