i've seen this debate before, and honestly i think people are too hung up on the shiny factor. sure, proxy APIs look sexy in the marketing, but i've been around long enough to see plenty of flaky API services come and go. old school list proxies have their flaws but at least you know what you're getting, more or less. the thing is, a lot of pros cling to lists cuz they understand them, they're predictable, and they don't break as often if you keep them maintained. if you ask me, the real magic is in how you handle the transition from lists to APIs, or even better, how you cloak your traffic once you have the right proxy setup. i've seen guys burn hours trying to troubleshoot flaky APIs only to realize they never tested their environment properly or they're using outdated techniques. proxy tech is still evolving, but don't get blinded by the new shiny. test everything, don't assume one is better than the other just because someone says so. seen too many guys get caught flat footed when a provider drops support or changes their API quirks. always have a backup plan and know your tools inside out.
