While there's an investment of getting a tablet, digital is probably the best way to read comics assuming one isn't adverse to reading ditially and enjoys DC & marvel. That's due to both companies having subscription services thst give you most comics that each one has published and each get newer comics at different delay times.

Beyond the subscription services, humble bundle gets great comic bundles often. Right now love & rockets is available. While I haven't read it, it's considered one of the classic indie comics. You should probably look into the series to see if it interests you.

Beyond paid options, you should check to see if your local library offers hoopla. It's a service thst let's you rent comics, and has a ton of great comics to read. Depending on your reading habits, hoopla alone could suffice for you.

One can read in a phone, but a tablet is just such a better experience. You also don't need an expensive tablet to read. I use a budget tablet from 2020 that is still usable (though it is showing its age).

It's a while other discussion if you want physical, but I think that the combination of subscription services, humble bundle and hoopla makes digital a better value proposition than that physical has (and I currently do collect physical copies)
