I prefer using tabs because the space constraint forces you to actually choose what's important to read. When there is no space constraint everything just gets dumped into a pile and there's no real way to prioritize what you truly do and don't want to read. You just end up with a long list of stuff you don't care enough to actually read.
At least that was my experience with Pocket. Maybe it works for some. I do the same thing with physical books. I don't keep a list of books to read. I keep a bookshelf full of stuff I'm making my way through over the years. Spending the money forces me to choose what I actually feel is important I read vs what I think I want to read.

It'll save them to a single page that includes all the previous tabs you've saved so you can cmd+f it if you REALLY want to find That One Thing You Had Open That One Time)
If you use that many tabs then you're better off using FireFox with the Tree Style Tabs extension [1]. Unlike the Chrome extension, it integrates properly with the browser window and you can hide the original tab strip.
