Been registering through the Icelandic lot for years and I've got no complaints — crypto, nobody asks for a name, WHOIS proxy included, and it's been the boring reliable choice since about 2018.
Problem is they don't carry the ccTLD I need for a client project and won't be adding it. Fair enough.
So who else in this space actually carries a wide TLD list? Every privacy registrar I look at has about forty extensions, and forty is fine right up until the one you need is the forty-first. In 2014 you could get anything anywhere and the trade-off was that the registrar knew everything about you; now the trade-off is inverted and I'm not convinced it's an improvement.
