Buying a (premium) service to get rid of something awful requires effort and resources.
Do you have the money? Do you get enough kicks out of the money you would be spending? Do you know the pros and cons of subscribing/going in a service (what will they provide for the money spent?)? Do you want to support the service - even so far to provide them money? You need to provide additional data of yourself to make the purchase and may even need to learn how to do it - are you ready for that?

Getting an (ad-blocking) extension to a browser to get rid of something awful requires effort and resources.
Do you know how to start using extensions in browsers and what to do if you need to troubleshoot them? Is it free (are paid extensions even a thing? I don’t recall seeing one)? Can you support someone you would want to support with a ad-blocker (some decent folks who make good content may be in need of the money they get from ads, but then again, there’s a chance you can send them money through other means)? Are you supporting a service that has an built-in feature that annoys you (in this case, providing ads for the users to see), endorsing such behavior (even more) even though you cannot see those ads yourself?

Both options may require research. Both options are influenced by other people and by their opinions. Both options have their pros and cons. Both options have consequences.

I don’t buy any subscriptions. I wouldn’t have the money for that and I have bad experiences of them.
I can support someone with a grateful comment or sharing their content to others.
I myself stick with the ad-blocking services.

But don’t let me influence you with what/how I do it 😉 Make up yer own mind and act accordingly.
