[Please Give Me Some Guidance On Proxies]

Hi guys, i've been browsing around on the BHW Proxy marketplace. All of these services look great and they all seem to be a viable option. My question is, what are most of you guys using these days? Storm Proxies? Changemyip.com? Smartproxy.io? Massproxy?

All of them look great, but I just want to know which service offers the most secure, stable, and strongest proxies. Thanks
