There may be no difference. Although...
You need to choose a registrar that provides complete information. Because registrars often hide the real cost of domain renewal. And after a year you have to pay 10 times more for domain renewal. I heard some registrars are blocking domains on complaint. And he doesn't even accept an appeal. I use a Pananimes registrar, there are no such problems. For 3 years already.
Namecheap is a really good registrar, and hostinger is a really good (AND CHEAP) host! I recommend those two companies!
I even transferred domains from other registrars to Pananames to pay less for renewals.maybe some high end domain perhaps, but most will not increase so much.
I decided to try it. I have already bought several domains here. By the way, the prices are set 10 years in advance, it's convenient.I even transferred domains from other registrars to Pananames to pay less for renewals.
