In 2023: not a ton. Maybe some better repeatability. You're likely to have fewer out-of-the-box problems; they spend a lot on quality control. If you're just interested in the hobby, the Elegoo Neptune 3 Pro is, for my money, a fantastic entrypoint that you can get for under $250. (I own the larger version, the Plus, which has a bigger bed and turns the fans off when not printing; it's sub-$350.) There's also the Sovol SV06 (and its larger Plus variant) in the same ballpark, though they're having some significant QC problems these days. It's also in the $200-$250 range. I have one of these too and it's pretty nice, but I have a first-run one before the QC problems started to rear up. The Prusa stuff is absolutely better made than the Sovol stuff--though the Elegoo stuff is remarkably high-quality, especially for the price--but frankly it is emphatically not four times better. The delta shrinks further if (and in this crowd, maybe when) you install the Klipper firmware to replace the stock Marlin stuff; Prusa's custom Marlin builds are better than the competition, but Klipper beats it all hollow, and the performance benefits of Klipper on the SV06 and the Neptune 3 Pro/Plus are huge when it comes to faster acceleration and thus faster printing.
