I have a bad impression of Bazel for multiple reasons. I wanted to build TF on the Pi but at the time I assumed it required Bazel. Bazel had no ARM version (my experience was in mid-2017). I had to first build Bazel from sources. Failed a few times because its heap settings were too low, required a lot more swap and storage than I expected, and got the Pi so hot that I had to quickly setup some cooling fans around. A successful build took ~1.5 hours on a RPi 2. Then the full TF build using Bazel took some 10-11 hours. Finally, Bazel's command-lines - ex: "bazel build --config=opt -k //tensorflow/tools/pip_package:build_pip_package" - felt very counterintuitive and not easy to remember. For the first two problems, I learnt it the hard way that a cross-compilation environment is better than building on-device. The last one I still have a problem with.
