Buying advice

Which should you buy?

The Titan 18 HX AI is the clear pick on raw spec strength, leading by 21.1 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Titan 18 HX AI if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are storage, ram, cpu cores, among others.

Pick the Galaxy Book4 Ultra if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are claimed battery life, weight.
