I've only heard the Aldrich pickups in videos where Doug plays them so I can't offer a whole lot of info on them. You'll probably be hard-pressed to find many who have because the Evo 2 is much more common. Now the Evo 2 is a bad-ass pickup. I like it better than the original Evolution which was pretty good but still lacked a little something. Now the Evo 2 has improved on that sound and really become a totally cool pickup.
I'm a big fan of Dimarzios. I've litterally bought and installed almost every Dimarzio and Seymour Duncan pickups there are, as well as several other brands. I used to think Seymour Duncan was the shit because of all the hype and because they were the first pickups I experimented with, but over the years I've really learned to respect Dimarzio pickups more.
I personally love the PAF Pro, 36th, Norton, Air Norton, Super Distortion, Evo 2, Breed and several of their single size humbuckers. I only really like 3 Seymour Ducans: Custom Custom, PATB 1 and Full Shred, but none of which I like more than Dimarzios.
All that said, let me tell you more specifics about the Evo 2. I've come to the conclusion that the original Evolution pickup is very well suited to basswood guitars. To my ears, basswood kind of dulls out some overtones. The Evolution, as I've heard it in alder body guitars, can be a bit harsh. The output is pretty damned high, more than I typically like to use. It's a cool pickup, but not as balanced as I'd like and a little too powerful for my tastes. I also just can't seem to find a neck pickup to go with it that I like 100%.
The Evo 2 on the other hand, is one hell of a pickup. It sounds better in other types of guitar woods and isn't as high-output as the Evolution. It sounds more balanced and seems to give you more control of your tone. It does clean up pretty well and sounds more organic than the original Evolution in my opinion. It also goes great with the Evolution neck pickup and a few others.
Your question though is too vague. I think there's a lot more to pickup selection than just "which one and why?" because there are factors like the type of body/neck/fingerboard wood, direct mount/pickguard, les paul/strat/superstrat/hollow type, musical style, amps, etc... Then you have to consider what neck pickup you'll use it with.
Plus, if you're going with high-output pickups like that, be prepared to work more for clean sounds or start considering a low-output middle pickup you can switch to for clean sounds.
I really liked the sound of a Super 3 but man it's so damned high-output that it really pushes the amp. I don't like pickups that are too powerful unless I'm specifically going for that kind of thing. The Evo 2 is a nice choice.
