Performance
Performance comes out as a tie. Lost Mary Viz lists 55,000 puffs against 50,000 for RAZ Vue 50K, but the gap isn’t treated as decisive given the other unknowns — RAZ Vue 50K states a 24 W max output while Lost Mary Viz doesn’t list one, and Lost Mary Viz names dual mesh coils while RAZ Vue 50K’s coil setup isn’t stated. With key figures missing on both sides, there isn’t enough matched data to separate them on raw performance.
Battery
Battery is also a tie. RAZ Vue 50K has a slightly larger 900 mAh cell versus 850 mAh on Lost Mary Viz, and both are rechargeable, but a 50 mAh difference is small enough that it doesn’t translate into a meaningful edge either way based on the numbers given.
Convenience
RAZ Vue 50K takes convenience mainly on the strength of its display, which Lost Mary Viz does not have. A screen can make it easier to track battery or puff status at a glance, which is the kind of day-to-day usability detail that tips this category even though other convenience factors like adjustable airflow are not clearly stated for either device.
Value
Lost Mary Viz wins on value largely due to its flavor lineup, offering 15 flavor options compared to 10 for RAZ Vue 50K. More flavor variety at a similar hardware tier is a straightforward value argument, especially since battery and puff count are essentially even between the two.
Lost Mary Viz suits buyers who want the widest flavor selection and solid value without needing an on-device display.
RAZ Vue 50K suits buyers who want the added convenience of a display to monitor their device at a glance.
The verdict
Neither device comes out as an outright winner once you look at the full spec sheet. Performance and battery are tied, RAZ Vue 50K pulls ahead on convenience thanks to its display, and Lost Mary Viz counters with a stronger value case built around its larger flavor selection. A few specs, including adjustable airflow, max output for Lost Mary Viz, and the coil type for RAZ Vue 50K, simply aren’t detailed enough to factor into a fair comparison. Which one makes more sense depends on whether a display or flavor variety matters more to the buyer.
