My experience with Bazel is it does everything you need, and works incredibly well once set up, but is ferociously complex and hard to learn and get started with. Buck and Pants are easier in some ways, but fundamentally they still look and feel mostly like Bazel, warts and all

I've been working on an alternate build tool Mill (https://www.mill-build.org) tries to provide the 90% of Bazel that people need at 10% the complexity cost. From a greenfield perspective a lot of work to try and catch up to Bazel's cross-language support and community. I think we can eventually get there, but it will be a long slog
