I've been using Luminati (now Bright Data) for test proxy needs, and it's been solid for geo-testing. Not the cheapest, but their IP rotation is smooth, and bans are rare.
For checking if a test proxy works, I usually run a quick curl command or use ProxyCheck.io to see if the IP is leaking. Speed tests matter too—nothing worse than a slow test proxy killing your workflow.
Free ones? Meh, they’re usually trash for anything serious.
