The ease at registering domains I think is what makes this service stand apart for me! There's no confusion about getting set up or navigating it once you're there - just pick something easy! And make sure your payment method allows payments through multiple currencies because some countries don't support all types so they'll get confused when doing international orders.
If anything were ever lost here my recommendation would be find another provider if possible (or backup yourself) but otherwise check everything before signing into an account/paying etc., especially where sensitive information like credit card details may go live via email confirmation. Easy access to web hosting services along side DNS records setup has been very useful over time now we have more than one website under different subdomains pointing towards same IP address using Cloudflare CDN platform.
