Results summary

Phone Y comes out with a clear lead, scoring 41.0% against Phone Z's 33.8%. This decision hinges almost entirely on camera performance, which accounts for nearly two-thirds of the overall weight. Phone Y's camera advantage over Phone Z is substantial at 17.4 percentage points, and this strength drives its overall victory despite the phone costing noticeably more and having a weaker battery.

The trade-off is straightforward: you are choosing a camera that matters far more to you than price or battery life. Phone Y gives up cost efficiency and battery endurance to get the camera performance you want. Check the sensitivity analysis to see whether this ranking holds if camera importance shifts even slightly.

Sensitivity summary

Phone Y holds a clear lead of 7.3 percentage points. It holds first place unless you substantially reweight the criteria. Camera is the most vulnerable point: decreasing its weight by about one fifth (from 63.7% to 50.5%) hands the win to Phone Z. More substantial shifts are needed to change the outcome via Price or Battery. Increasing Price's weight from 25.8% to 44.4% would lift Phone X into first place, while increasing Battery's weight from 10.5% to 22.4% would favour Phone Z.

All three criteria can swing the result with the right reweighting, but none will flip the winner by a small adjustment. If Camera matters less to you than your current weights suggest, Phone Z becomes the stronger choice. Otherwise, Phone Y's lead is secure.
