I don't have any distinct cpu/memory/battery profiling datasets to provide anything but a personal anecdote. I dropped Chrome due to general laptop responsiveness in favour of a combo of Firefox with AdNausem and Privacy Badger. Which, has worked fine for my use (not noticed any adverse battery effects but I've also not been actively monitoring), though I don't use nearly the number of google services you've listed. Your results may differ, I've heard mixed reviews (again, anecdotally, so take with a grain of salt) of google services in firefox and safari.
