The verdict
Buy the Neptune 4.
8.2/10 vs Saturn 4 Ultra's 7.8/10, and it wins 3 of 5 categories. Very close race with the Ender 3 V3 KE. The KE has WiFi, this has a slightly larger bed. Pick based on brand preference or which one is in stock. Neither is wrong.

Pros & Cons
Neptune 4
- +Klipper at this price means real input shaping and pressure advance, not just fast travel speeds
- +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
- −Elegoo's community is smaller than Creality's, which matters when you hit unusual problems
Saturn 4 Ultra
- +218x123mm plate fits a full Warhammer squad in one run, not two
- +12K resolution holds up just as well as the Mars at 14K for most print sizes
- +Tilt release is worth it at this plate size: peel forces on large prints are brutal without it
- −Resin consumption goes up fast when you're filling a plate this size
- −Post-processing for a full plate run takes 45-60 minutes minimum
