THE VERDICT

G203 Lightsync is the stronger buy for most people because it combines the broader spec lead with a more defensible price. G305 is not a bad pick, but it only makes more sense if its narrower strengths line up exactly with your workload.

Buy G203 Lightsync if you want the safest all-round choice in this price tier.
Pick G305 only when one of its standout strengths matters more than balanced value.
Do not compare these two in isolation; keep your actual budget ceiling in view.
