Recommendations for dynamic DNS?

I currently connect to my own VPN server via its IP address directly. This works only as long as its IP stays the same. However as soon as my ISP decides to switch its IP I won’t be able to connect to it anymore.

Therefore I’m looking for a dynamic DNS solution like DynDNS or No-IP.

Considering that IP address and URL are public information anyway, does the choice of which dynmamic DNS provider to pick matter or should I just not think too much about it? ^^
