I think Madara felt sasuke was just like him, his EMS was similar to Madara and he also awakened his rinnegan from his sharingan just like Madara did. Madara was also impressed by sasuke's battle intelligence and judgement. Sasuke was also headstrong in his conviction ,unlike obito as he wavered at the end. I don't think Madara compared both sasuke and obito in terms of strength. Madara was sold when Sasuke, fighting Madara with his rinnegan,he broke down the working of limbo and even devised a plan to counter it. Sasuke would have been stronger with the hashi cells and ems, chances are he would have awakened his rinnegan too( though if Madara was alive when he found Sasuke then Sasuke could not have become indra's transmigrant).
