Would having our own domain name much better than driving traffic directly to the affiliate links?

I am planning to buy some domain names and also considering of postponing the plans to buy them.
Are there real benefits to buying/owning our own domain names and forward it or provide a link to affiliate links?
Thank you and looking for advice.

Ofcourse, and the best part is you can try and collect mails before sending them to your affiliate links

Prelanders are always better. Among many other benifits, those I see thats most beneficial are that they allow you to gather data from your visitors and retarget them on other offers as well as being able to stand out against the competition.
