As far as I know and from what I have read in different sources, mobile proxies are considered the most stable tools, and their pricing reflects that. On one hand, you always want to choose the best and most convenient option, on the other, is it really worth overpaying? You can use selectors like https://floppydata.com/proxy-selector/ to understand whether you actually need to pay for a mobile proxy or if something simpler will work just fine.
