The verdict
Tied at 7.8/10. Buy the Mars 4 Ultra, $219 less.
If you're choosing between the Mars 4 ($149) and this, spend the $91 more. The tilt release alone extends FEP life enough to justify it. The 9K detail is also noticeably sharper on fine models.

Pros & Cons
Mars 4 Ultra
- +9K resolution is a meaningful jump from 7K: finer surface texture, sharper edges on small parts
- +Tilt release means FEP films last longer; $50 less per year in consumables is real money
- +Built-in air purifier takes the edge off the smell without requiring an external solution
- −153x77mm plate is tight for anything larger than small character models
- −Still needs a wash and cure station: budget $50-80 extra
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
