For me right now as a submitter, I'm only looking for online or online+print magazines that are stable, attractive, easy to read, and publishes work that I want to read. Organizational stability - that is, the magazine isn't likely to fold within a few years and take my publication with it - is the most impotant of all of these to me. When an online magazine disappears, work I published in it goes into a limbo - neither available to an audience, nor something I can submit to journals that don't do reprints. I truly understand that sustaining a semi-permanent online archive requires a lot of work + money, I truly understand that magazines fold when they need to! But for this reason I only submit to magazines that have already existed for years, have a masthead that make it seem like a sustainable team project with legacy planning and not a solo person's passion project, and ideally institutional support like being part of an MFA program or larger nonprofit. Some of these aspects I can kind use Chill Subs and/or rankings like this one to approximate, bc award-winning (etc) journals tend to have existed for longer, etc. So that's why I find these lists useful!
