I think it will depend on how much versatility you want in your pickups. The Aftermath will be better at more aggressive styles and be tighter if that's what you're after but will have limited versatility. Conversely, the Holydiver has a far sweeter tone and is a lot more versatile but doesn't have the aggression of the Aftermath. If you move to the Miracle Man, you stay with something that is surprisingly close to the Holydiver tonally but is tighter and a little more scooped, though this isn't as scooped as the EQ chart suggests. To get this however, you do sacrifice some of the Holydiver's versatility. I've never really warmed to the Juggernaut set myself so it's difficult to comment. I really like what it's trying to do and it sounded perfect for me when it was first announced but I've just never heard a clip that's impressed me so I eventually went with a pickup elsewhere that tries to do the same job but does it more effectively.
For the neck, an Emerald is an ideal choice to pair with the Holydiver and is hot enough to work well with the Miracle Man too. I've had a Cold Sweat neck and I did like it but the Emerald and Holydiver neck options were both better in my view.
