They're definitely so very similar in that way. It's obvious enough that even Madoka herself kind of realises it.

So much so that - after the slightest moment of hesitation - she even manages to slightly tease him about it. Maybe it'll make him feel a tad better.

"I bet he won't be buying everything for himself even then." The implication being that she's sure Ignis will still buy him presents, of course. (And she can't blame him, Noct is so nice! How can anyone not want to be super nice to him?) It's said with a slight smile to show she's just teasing.
