they are Duncan's most popular neck Humbuckers for a reason & they sound absolutely great in L.P.'s! I like something a bit more exotic in my fiddles but the Jazz is a great pickup, I mean hundreds of thousands of guitars can't be wrong???
A Duncan '59 is usually what I swap in when I want LESS bass response.
Then apparently you're not putting them in LP's, as that's where most of the 'boomy' complaints come from, and of course, the OP has an LP.
Better choices for him are an A2P if he wants a little high-end edge to it, or a PGN if he likes warm, rounded high-ends.
you make a lot of assumptions... my Dean Soltero USA, a guitar which I'm sure you wouldn't even be able to afford.
Fact
A A2P would also be a great choice but I still think the Pearly Gates is a hard pickup to beat...
