What's the difference between EMG Active 81/85's and Duncan Designed Active HB-105's?

-What's the difference in tone and sound between the two? I have the option of each with a new guitar I'm buying.It depends on what tone you want out of your guitar. I have EMG's in my guitar and i dont really like them but thats just cause im looking for a better low end bite on my 7 string. I'm planning on replacing them for a seymor duncan blackout in the bridge and a Bareknuckle humbucker in the neck possition. I have the same 6 string combintation in my 6 string guitars and i really like the combination of the two. But if you dont habe the option of getting a different option I recommend the Emg's cause i have had duncan designed pickups in my schecter guitar and i hated them so much they were out of my guitar in one week and i replace them with a dimarzio x2n in the bridge possition and a dimarzio d activator in the neck possition. I use two different pickups in each of my guitars for more versatility cause the duncan blackout is good for metal in the bridge possition and i want a cleaner humbucker in the neck so you can get the b est of both worlds,
