The Galaxy Watch 8 Classic has a few perks over the Watch 8 to justify the extra $150, but it mostly boils down to stainless steel style and the physical rotating bezel. Since style is subjective, I'll focus on the more quantifiable second perk: Is the rotating bezel worth it, and will you like how Samsung changed it?
Both the Galaxy Watch 6 Classic and Watch 4 Classic had rotating bezels around their displays, hearkening back to the original Tizen OS Galaxy Watch design. Physical controls define the "Classic" experience as much as the retro chic; it's why so many Samsung watch fans skip alternating years to avoid the mainline models' digital bezel.
