Pros & Cons
Bambu Lab P2S
+Quick-swap nozzle: no tools, no waiting for cool-down, no thread damage from hot-tightening

+AMS 2 Pro dries filament while printing so you don't need a separate drybox for standard materials
+5-inch touchscreen is large enough to actually use without squinting at a 2-inch screen
−No LiDAR sensor: that capability is still exclusive to the X-series
−P1S owners have no trade-in path; the upgrade cost is the full $549
−Multi-color purges still waste filament; purge blocks help but don't fix the root issue
−The $799 Combo version gets close enough to the H2D's price that a comparison is warranted

+Direct drive handles TPU without a fight
+500mm/s capable on stock profiles

−No WiFi on the base model: Elegoo charges extra for connectivity the KE includes free
