Could you share some of those competitors? I've tried a few VPNs which have not been especially fast, e.g. https://ovpn.com. Would like to find one that supports IPsec, which is supported natively by several operating systems.
PIA (yeah, I know they are owned by a dodgy company now, and I sound like a shill by suggesting them) does really well. No problem maxing a gigabit connection, and their peering is even better than my ISP a lot of the time - I get lower latency when playing games on US servers when using their network. I reluctantly signed back up after having speed issues w/ Mullvad.
