I am going with option 3 for the VPN and originally ordered two Opals for configuration but did a speed test and saw I have 150 mbps for both download and upload speed. Is it worth it to upgrade to Beryl or Slate since they have higher max speeds via wire guard? If so, should both my home and travel router be updated or just one of them?

For reference the listed wireguard speeds: Beryl - 91 mbps Opal - 65 mbps Slate Plus - 170 mbps
