Both setups solve the same underlying problem — needing more visible screen space than one standard monitor provides — but they solve it differently enough that the "better" choice depends heavily on what you actually do at your desk.
Two monitors side by side means a visible seam of bezels running down the middle of your view. For tasks where content needs to flow continuously across the screen — video editing timelines, wide spreadsheets, CAD work — that seam is a real interruption. An ultrawide has no interior seam, which is the single biggest reason video editors and designers tend to prefer it once they've tried both.
Dual monitors let you angle each screen independently, which matters if you frequently reference something directly to your side rather than in your central field of view. They're also more flexible if your work genuinely splits into two separate contexts — for example, a dedicated communication screen (chat, email) that stays constant while the other screen changes task. An ultrawide can be split into virtual sections with window-snapping software, but it's still one physical surface you're scanning, not two independently angled ones.
A quality ultrawide typically costs more than two mid-range standard monitors combined, but takes up less physical desk depth and needs only one stand or arm instead of two. Dual monitor setups are usually cheaper to assemble from scratch, especially if you already own one monitor and just add a second.
For gaming specifically, ultrawide has become the more common recommendation because a single high-refresh-rate ultrawide avoids any bezel interruption in your field of view, and most modern games support ultrawide resolutions natively now, which wasn't reliably true a few years ago. Dual monitors for gaming genuinely only make sense if the second screen is dedicated to something else (chat, a stream overlay, a guide) rather than extending the game across both.
Bottom line: there's no universal winner. Match the setup to how your work actually flows — continuous content favors ultrawide, fixed-reference multitasking favors dual monitors.

For most coding work, yes, since a wide window can show long lines and side-by-side files without a bezel interrupting the view — though some developers still prefer a dedicated second screen for docs or a terminal.
Yes, with window-snapping software (built into most modern operating systems or available as free utilities), an ultrawide can be divided into two or three virtual sections, though it remains one physical display being scanned rather than two independently angled screens.
Usually, especially if you already own one monitor and only need to add a second mid-range one. A quality ultrawide typically costs more than two mid-range standard monitors combined.
What might change: software support for ultrawide resolutions in games and OS-level window snapping improves regularly — recheck current compatibility for specific titles or systems.
