I think not all gen parts and replica parts are created equal. There are some extremely nice watches here, like the Daytonas and big crowns.. builds that cost thousands, yet do not meet the criteria for "Frankenstein", although they are in many cases more beautiful and more accurate than builds with >50% gen parts.
In my view, the selection of parts, modding, fitment, and the aesthetic eye to maintain balance and pull everything together in the finished watch, is far more important than counting the number of gen parts. In the end, it matters very little to me if it's classified as rep, franken, genstein, etc.
