No single model is explicitly ranked as preferred; the four columns of Table III are robustness variants 'differentiated by the exclusion of variables' (p.603) and the paper reports a summary 'Mean Elasticity' line for each. I mark the headline Mean Elasticity obs as preferred. || 'Table III reports estimation results, including short-run price elasticities ... for four versions of the model differentiated by the exclusion of variables.' (p.603)
