Gamma RCF-Obsidian 13 vs Gamma RCF-Obsidian 16
The Gamma RCF-Obsidian 13 is a 13 mm elongated paddle; the Gamma RCF-Obsidian 16 is a 16 mm elongated one. Across the 6 specs with a clearly better direction the RCF-Obsidian 16 takes 4 and the RCF-Obsidian 13 takes 1. The RCF-Obsidian 13 swings lighter (116.0 vs 120.0) — quicker hands at the net, where the RCF-Obsidian 16 plows through the ball instead. That is a preference, not a win. They retail for the same $159.99.
Two paddles from the same brand, so the differences are the ones the maker chose. Every number below is lab-measured, not a manufacturer claim.

Static weight 8.0 oz vs 8.1 oz — a few grams of tape moves swing weight far more than static weight, so either can be pushed toward the other.
