They’re all about the same, just look at the thickness of the pans when deciding which one to buy. A thinner (~2mm) one will be a lot more reactive to temperature changes whereas a (3mm+) pan will be a much better tool for searing. The differences aren’t drastic enough that you need more than one unless you enjoy collecting. Premium brands aren’t necessarily going to perform better than cheaper ones, but I don’t think this necessarily means that they aren’t worth it. These pans should last more than a lifetime (my oldest has been going strong for a decade now), so if you’d like to treat yourself and have the means to do so, I say go for it. Things to pay attention to when comparing brands would be the cooking surface diameter, slope on the side walls, handle design, and whether or not the pan is riveted for easier cleaning.
The two relatively popular exceptions to the rule of all carbon steel being about the same would be Strata and Misen’s Carbon Nonstick. Both are tri-ply pans with an aluminum mid layer, so they should be significantly lighter and more reactive than pans of similar thickness. Misen’s take comes with a treatment on the steel that supposedly makes it less prone to sticking and unreactive to acidic foods. I’ve never tried the Strata, and I’ve not had Misen’s pan long enough to speak to the longevity of the treatment, but I can say that it was definitely less sticky than untreated carbon steel pans out the box (though with proper preheating it’s not a huge deal). Acidic foods do still strip seasoning off of the pans, but the treated base layer doesn’t rust so you don’t have to be paranoid about cleaning (though I would say not to be paranoid no matter what pan you get). If you or someone that you know may struggle to handle heavier pans, both of these options are great.
