These two are nearly even on the Mars Score (77.7 vs 79.3). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the DeathAdder V4 Pro if you care most about battery / max dpi. Its strongest claims are battery, max dpi, buttons. The single most decisive one: Battery — 87.50% more. 150 h vs 80 h.
