The verdict
Buy the Neptune 4 Pro.
The P1P scores higher but is discontinued. The Neptune 4 Pro is the move if you want linear rails without paying Bambu prices. The Creality V3 KE is the comparison to make: same price, different ecosystems. Creality wins on community, Elegoo wins on hardware spec for the money.

What owners say
Same guts as the P1S at a lower price. If you add enclosure panels, you basically have a P1S.
P1P owner, r/BambuLabBambu quality, CoreXY speed, open frame flexibility. Solid machine.
P1P owner, Thomas Sanladerer (YouTube)Linear rails at [this price] is wild. This thing flies.
Neptune 4 Pro owner, r/3DprintingElegoo came out swinging with the Neptune 4 series. Solid contender.

Pros & Cons
P1P
- +Identical CoreXY motion system as the P1S: same speed, same print head, same quality
- +Aftermarket enclosure panels are cheap and turn this into a near-P1S for less money
- +Bambu's slicer and cloud ecosystem work the same as on every other Bambu
- −Open frame when the cheaper A1 Combo includes AMS Lite: the value math is awkward
- −AMS sold separately: the one thing the A1 Combo has that this doesn't
Neptune 4 Pro
- +Linear rails at this price is a feature you normally pay $400+ for
- +Klipper pre-installed with decent out-of-box profiles
- +500mm/s sustained prints well with stock settings
- −Early units shipped with firmware bugs that needed patching
- −Elegoo's support community is a fraction of Creality's size

- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
