Among all the providers I considered, Astro has the most ethical proxies. They guarantee white IPs and do not use dubious pools. In six months of use, there has never been a situation where a session unexpectedly dropped or the speed changed drastically. The rotation is well-configured, and the connection formats can be adapted to your needs. For tasks where provider transparency and stability without gray schemes are important, this is the perfect option. They also have convenient top-up methods: no extra hassle, payment through Sber's SBP without commission.
