The Callaway Quantum Max and the Cobra KING are both game improvement sets built on hollow bodies with stronger lofts, and both run 5-iron through PW. The KING is 0.5 degrees stronger at the 7-iron, 27° against 27.5°, which works out to roughly 1 yard more carry at the same swing speed. Check your wedge gapping if you switch. The real split is in construction and price. The Quantum Max is the only one tagged with an AI Designed Face. The KING is the only one tagged Multi-Material with a Face Insert, and it lists at $1,099, $100 under the Quantum Max at $1,199. The KING also carries editorial recognition, with Golf Digest scoring it 78/100 and MyGolfSpy 84/100. The Quantum Max has none on file.
On the facts available, the Cobra KING is the stronger buy. It costs less, it is fractionally longer, and it is the only one of the two with published scores from Golf Digest and MyGolfSpy. Pick the Callaway Quantum Max if the AI Designed Face is what you want in a hollow body iron, or if the slightly weaker lofts fit your current wedge gapping better. If price or outside validation matters most to you, the KING is the clear choice.
