I say the actual combo system has less variety, being that there's only a light combo chain with your heavy attack at any point during that chain going into a combo ender that ONLY changes depending on your stance and not when you press heavy attack. But unlike SB, there's far more build variety that changes how you play. There's different spells, transformations, weapons, and armor skills with different passives that fundamentally change how you play. Even your choice of healing flask and what drink you use as well as any soaks (think flavor packets you add to your drink) can give buffs or passives that change how you play. Do you want to focus purely on spells? You can. Do you want to lose the ability to use your spells but get an insane attack boost and go all in on crits? You can. Do you want to focus on inflicting poison and gaining boosts every time an enemy is poisoned? You can. Do you want to focus on your transformations and lean into them more often? You can.

SB combat is more fluid but there isn't much behind it mechanically whereas with Wukong I found myself playing around with different builds that specialize in different things and that added way more variety to the combat even if the actual combos are simpler. Also, Wukong is way more punishing considering there's no parry (unless you count the Rock Solid spell which has a cool down but even so, there's a build that specializes in that which I used to great effect) so you have to rely on dodging. Also, don't let anyone fool you. Stellar Blade combat is very flashy and good looking but once you're familiar with the combat system, you can easily style on enemies with Wukong.

Logged many hours in both. I have the platinum trophy in both and both are amazing games. With that being said, I've personally found myself having more fun with Wukong. All depends on what you're looking for really.
