I’d probably avoid treating it as a strict either-or choice. I’ve used datacenter proxies for quick testing and general tasks, while residential ones have been more useful when I needed a broader mix of locations. When I was checking how something behaved from Italy, I looked through
https://www.simplynode.io/locations/italy-proxies to compare the available options. In my experience, the right choice depends heavily on the project, the locations you need, and how important stability is. Sometimes paying more for residential IPs makes sense, but other times a simple datacenter proxy does everything you need without adding unnecessary cost.
