Despite the rapid growth and popularity of the .ae ccTLD, .ae domains can only be registered through a handful of accredited registrars (full list: https://tdra.gov.ae/en/aeda/accredited-registrars). With whom you choose to manage your domains through is a matter of personal preference.
Some reputable registrars include:
AEserver.com
NIC.ae
Tasjeel.ae
Buzinessware.com
OnlyDomains.com
101Domain.com
You cannot register, transfer, or manage domains through GoDaddy.com, Name.com, NameCheap.com, or any of the more popular domain registrars.
