With digital assets there is always an element 'trust' involved, there are a few stories of people getting screwed over with NFT's and crypto, but there is not one company (high profile company) that I can think of who have deliberately gone out of their way to screw someone over, I think we are fortunate in that way as far as domains is concerned.
A few individuals come to mind, but in terms of big companies (Escrow.com/Sedo.com/GoDaddy.com etc) reputation and trust is a big thing and truth is I think all are very trustworthy.
I tend to keep my domains with the same company so in terms of companies most of 'my' trust is on:-
NameSilo.com
Escrow.com (when i make a sale)
But have done business with Dan.com/GoDaddy.com/Sedo.com and all have been great to deal with.
