Which one is faster at the kitchen line?
GAMMA Obsidian 16, at 102 kg·cm² swing weight against 110 for Franklin Signature Carbon STR. Lower swing weight is the single best predictor of hand speed in fast exchanges.
Which paddle has more power, the Franklin Signature Carbon STR or the GAMMA Obsidian 16?

Which one gives more control and touch?
GAMMA Obsidian 16 at 86 versus 83. Its 16 mm core holds the ball on the face slightly longer, which is what makes resets and dinks land shorter.
Which paddle spins the ball more?
Franklin Signature Carbon STR scores 80 for spin off its Raw carbon face, against 74 for the Textured graphite composite face on GAMMA Obsidian 16. In practice a 6-point gap is noticeable on third-shot drives.
Which is more forgiving on off-center hits?
GAMMA Obsidian 16, with 6.2 twist weight against 6. Higher twist weight means the face rotates less when you miss the middle, and GAMMA Obsidian 16 carries the higher forgiveness score (88) as a result.
Is the price difference worth it?
Franklin Signature Carbon STR costs $110, $40 less. Whether that gap is worth closing depends on whether you actually use the traits it trades away — check the head-to-head DNA bars above before paying up.
Do they use the same core and face?

Which one is better for beginners?

Which is lighter in the hand?
GAMMA Obsidian 16 at 7.7 oz against 8 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (102 vs 110) is what you feel mid-rally.
