I'd say #19 is superior based on his durability feats. Regardless of which is stronger though, the OP not specifying that there'd be no energy absorption allows means #19 definitely takes it.

Those were originally supposed to be the Androids Trunks couldn't defeat. 19 wins.
I don't disagree with your conclusion, but I wouldn't say this being Toriyama's original intent is a solid reasoning for it. What he originally planned doesn't really mean much compared to what he did, since he's went back on original plans several times before (Saiyans being the strongest warriors in the universe, Gohan becoming the main character, etc.) and even bothered to add conflicting evidence prior to the reveal (eg. Vegeta saying #19 and #20 weren't as scary as they'd been hyped up to be).
