Do I need an ENS domain?

Hello there, could you please elaborate on this matter for me? I've been hearing a lot about ENS domains recently and I'm quite curious about them. So, my question is - do I actually need an ENS domain? What are the benefits of having one? And if I decide to get one, how should I proceed? I'm a bit overwhelmed with all the information out there, so your insights would be greatly appreciated. Thank you in advance for your help!
