I can't say for sure, but here are a couple of my thoughts. Let me start by saying I ADORE the score and play both recordings all the time.
1. It's a charm show, not a blockbuster. The original production ran 300 performances, which wasn't bad for a small cast musical opening on Broadway within the same 12 months or so of HELLO, DOLLY!, FUNNY GIRL and FADE OUT, FADE IN. (The latter was actually the biggest grosser of the three in its day and closed because its star, Carol Burnett, left abruptly, not because audiences weren't buying tickets.)
Even those of us who like Jerry Herman and Jule Styne might well argue that SHE LOVES ME's score shows more skill, but the evening as a whole doesn't generate the same excitement that sends people home to call their friends and scream, "You MUST see this show!" It will be interesting to look back in a few years, but I think we will be able to make the same comparison of FUN HOME and HAMILTON (I write, having seen neither show). FUN HOME is obviously a hit, but I doubt it will be the mega-hit that HAMILTON is proving to be.
2. Nobody likes to hear this, but I think SHE LOVES ME has some subtle second-act problems in its book. Once George sings the title song, the main plot is over; we know he and Amalia love each other and can only wait for the fact to be revealed to her. Meanwhile, there is the winding up of various subplots, none of which carries anything like the emotional weight of George/Amalia. And no matter how much we admire the brilliance of "A Trip to the Library" and "Twelve Days to Christmas", the one time I saw an actual production, I could feel the excitement of the audience deflate as they waited for a play to conclude when it felt, for the most part, already over.
(Other shows I love, including CARMELINA and THE BRIDGES OF MADISON COUNTY have similar problems: they don't quite end; they end and end and end. INTO THE WOODS would be another example if it didn't have that catchy title tune as a final reprise.)
The deflation of SHE LOVES ME's last 30 minutes only increases the feeling among many spectators that the show makes for a pleasant evening, but not an unforgettable one.
Obviously, all of the above is IMO only and let me reiterate that I am a SHE LOVES ME devotee (it is by far my favorite Bock and Harnick show) and I LOVE the songs at the end of Act II. It's the story that peters out erratically, not the quality of the score.
(ETA I agree that the show isn't dated, unless one thinks every score that isn't hip hop is hopelessly old-fashioned.)
