I've been using LMSYS as the best available high level "these are models to pay the most attention to" benchmark - I've not seen anything else that's nearly as useful on that front.
The other one I consult occasionally is https://gorilla.cs.berkeley.edu/leaderboard.html - the Berkeley Function-Calling Leaderboard - because function calling is a really useful characteristic of smaller models.
I believe the best ways to evaluate these models is with your own set of task-specific evals for your own project, but these are REALLY difficult to construct. I still don't have a good solution there for my own work.
