Recommendations best premium DDNS service

I've used DynDNS's DDNS service for years (for my custom domain name). It allowed me to create ad-hoc sub-domains easily and quickly. Since they've stop offering DDNS, I have no choice but to switch to an equivalent service that I can trust.

Since I'm using my Asus router's builtin DDNS client (Merlin), I'm limited to which services I can use. Could someone tell me which one offers the best prermium DDNS service with good tech support in the list below. I only recognize no-ip.com and freedns.afraid,org.
