One big perk in my eyes is they are specific to businesses and there are counter-signed legal agreements, contracts in place. As such, far less likely to pull a stunt like another registrar recently that put a domain on hold [1] for one abuse complaint. They would instead reach out to the multiple business leaders listed as business contacts and sort things out like professionals. They also have a legal presence in every country where it is required to get the ccTLD of that country. I never had a bad interaction with them and they were always reachable and knowledgeable.
I have had good luck thus far with eNom for my hobby domains and Porkbun for my meme domains.
$100-$500/yr for a .com is what I've heard, and a minimum spend for other things, such as registry lock.
