Pros & Cons
Bambu Lab P2S
+Quick-swap nozzle: no tools, no waiting for cool-down, no thread damage from hot-tightening
+1080p AI camera pauses the print when it detects layer failures, not just notifies you
+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
Elegoo Neptune 4 Max
+420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
+Direct drive on a bed this large is unusual and useful for flexible materials
+Klipper gives you full control to tune speed and acceleration for the mass of this bed
+Prints full armor breastplates in a single run
−Open frame at this scale means ABS warping will ruin prints without serious prep
−The sheer footprint means a dedicated table minimum; don't try to share desk space
−Slower effective speeds on a 420mm heated bed: physics wins eventually
