I'd need a good read that tells me I'm ahead for sure before declining my shot at a free showdown. Some of the good things about this board is the pair of fives out there which presumably haven't hit him, and the jack on the river could easily have improved a straight draw to top pair. So you have a great chance to get called by JT, QJ, and J8, who all improved on the river. But if you routinely value bet the river with marginal hands your opponents may start playing trickier against you with their big hands which you don't want to happen.
