Clean sweep of the Spider-Man trilogy.
For all of their faults and "inaccuracies," Raimi's movies (even SM3) had real heart, and a sense of joy and excitement for the material and its world. That's a rarity in blockbusters, I actually find it to be more the exception in the MCU (the first Iron Man, Avengers, and GOTG, being the ones) too. Spider-Man 2 also remains a benchmark that, at least judging from the trailer for Homecoming, will remain unchallenged in its own character's movie franchise.
With that said, I will defend the X-Men a little bit. I see folks throwing around the word "overrated," but the truth is that without the X-Men and Spider-Man franchises both, we wouldn't have the MCU to date. And the only one of the original X-Men films that is uncompromised is X2. X1 didn't have the budget or time it needed to succeed fully, and X3 was a studio rushed hack job. But X2 holds up quite well as one of the better superhero movies made to date, and certainly of its era. And even in X1's defense, its strong casting choices overall (excluding Ms. Berry) and focus on characterization, and allusions to WWII and gay rights is why the movie helped wash out the taste of Batman & Robin in the industry, as well as become a staple for marginalized minorities who had it much rougher in the Bush Years than they have had since Obama was elected.
.... And as for today, I'll take X-Men: First Class and X-Men: Days of Future Past over pretty much the whole MCU. But I suspect that has more to do with Matthew Vaughn and Jane Goldman taking what Singer created and vastly improving it. Apocalypse was Singer/Kinberg on their own, and well... it was far below most of the MCU then.
