auctions Latest recommendation for auction site / opinion on SAV.com?

[Paperhand]

HI, I know there has been quite a few discussions about the right place to put domains up for auction, but I would be interested in your updated opinions. I would like to test the water for some of my GPT and AI related domains and have been regurarly checking namebio. Since they have been quite a few relatable sales, and also bc it is free, I put some up for auction there, but am not really convinced whether it was the right choice: I pointed the nameservers to sav, but most of those domains just generate an error message after working properly before. Also, there is no backend to have an overview of the ongoing auctions.

I will try godaddy too, but I would really like to read your opinion on your preferred auction site, or maybe more in detail, preferred auction site for this kind of domains.
