This is a bad take and a false dichotomy. The reasons for choosing a library or a service are so myriad and context-dependent that any generalization about which is "better" is just silliness. It's like saying, "If you have to get somewhere, running is better than walking." Sure, in the case of a race or escaping a predator, running is probably the best option. But what if you want to take in the sights or you can't sweat in your clothes? Running would be a bad choice, even though it's faster. There are just too many variables in the real world to make any sort of blanket statement about which approach is "better."
