Great topic — choosing the right proxy depends a lot on purpose and risk tolerance. For many uses,
shared datacenter proxies are a cost-effective option and deliver high speed and large bandwidth, but they tend to be more easily detected or blocked by sites because they originate from known data-center IP ranges.
On the other hand, if you need more stealth (e.g., multi-account work, harder anti-bot defence) you may want to look into residential or mobile proxies — though at higher cost and possibly lower throughput.
So in short: pick shared datacenter proxies for bulk volume when detection risk is moderate; pick higher trust proxies when you need lower visibility.
