Why choose Abseil for associative containers? It was a big deal when it first appeared on the scene, and it's certainly still better than the standard library for the most part, but there are now a number of alternatives that have since improved upon its weaknesses. (I've been especially impressed by Boost's unordered_flat_map.) I have increasingly soured on Abseil over the past couple of years. At Google, we've seen an exodus of many of the core library maintainers, and some of the more recent design choices have been questionable at best.
