Quick answer: Neither time nor moves is universally more important. Time measures pace and recognition, while move count measures route efficiency. The cleanest way to improve is to track both separately on the same Game Number, draw mode, deal type and difficulty.
Time measures how quickly you recognize and execute
A fast result can reflect quick scanning, familiarity with the deal, confident stock handling and fewer pauses. It can also include more temporary moves if speed matters more than route efficiency.
This is why a fast game is not automatically a low-move game.
Moves measure how much work the route required
Move count highlights rearrangement. Rebuilding sequences, moving a King twice or making optional transfers can increase the number even when the final time is fast.

Different deals should not share one benchmark
A difficult deal may require more manipulation than an open deal. Comparing a three-minute win on one shuffle with a four-minute win on another does not isolate skill very well.
Same-deal comparison controls the starting position and makes both metrics more useful.
Use time when practicing pattern recognition
Replay a familiar deal and try to reduce hesitation while keeping the route sound. This is useful once you already understand the decisions and want smoother execution.
Use moves when practicing efficiency
Replay the same deal and ask which transfers were temporary, duplicated or unnecessary. Try to preserve sequences and avoid moves that create no new access.
Personal bests should stay metric-specific
A new fastest time and a new fewest-moves result are separate achievements. One attempt can improve time while using more moves, or reduce moves while taking longer. The result UI should report that honestly rather than compressing both into a single claim.
What should a beginner optimize first?
Win consistently first. Once the rules and board scan feel natural, use moves to improve decision quality and time to improve recognition speed. The Classic Solitaire scoring guide explains how the site presents these metrics.
