The MK video was a better video. The edits were amazing.
I don't know if that is indicative of the games getting more hype than the other though.
If I had a hot take on this I would say the MK overall has seen a more significant upward trend in its history than Street Fighter which has several missteps and games that barely managed to maintain the bar. SF is my favorite fighter that's still active but it's far from perfect and at this point in the series, I don't think perfection is an unrealistic expectation.
