We should compare fish using displacement. My advice, take measurements, weights, pictures, etc. to document your progress, and don't worry about what the internet says. My smallmouth looks like it could probably eat both those largemouths, and it weighed several pounds less than either. I don't remember exactly how long it was, something like 21". It weighed 5 lbs. 10 oz. Pictures all lie, so make them at least look good.
