IVPN is very similar kind of focus and branding, same with Obscura.

The ones I can recommend that aren't on this list are Obscura and Nym.
I think this is a good rule of thumb: "If a company invests so much money in advertising over the long term and promotes its products so aggressively, the product must be subpar."
Mullvad and IVPN both don't do affiliate links. Proton is the only VPN that I can recommend that does use affiliate link marketing. They also do a lot of sponsorships. Proton really is a great company with great products.
