I've tried a few different proxy services for remote desktop access, especially when I needed a US IP for work projects. What really mattered for me was consistency, some proxies dropped connections too often or got flagged, so having a smart proxy setup made a big difference for smooth logins and keeping everything secure.
If you want a flexible approach and more options for your access, you could also check out solutions focused on data crawling and proxies. I came across this at
https://crawlbase.com/ when I was researching web data and proxies for another project; their smart proxy service is pretty reliable and worth a look if you want something robust.
