The practical thing that decides this is range. Garcia's reach and hand speed mean Benn eats clean counters all night, and that either stops him or buries him on the cards. Benn's case rests on pressure, work rate, and heart, and I get why that's appealing. He's tough, he digs to the body, and fans love that style. But pressure only works if you can close the distance without getting cracked, and Benn's defense is leaky. A fast counter puncher lives in exactly that gap. Garcia is the taller, longer, naturally bigger man, and the power he showed at 140 and above is real. Benn has been hurt before by guys who don't hit as hard. So the honest read is Garcia by stoppage, or at worst a clear decision.
