That's... a pretty vague line of questioning.
Tried the Blackouts once and immediately swapped them back out, never cared to try them a second time. To me they sounded like they were made to split the difference between a single coil and a humbucker, like they were a pickup for someone who wanted an active HHH sound but was stuck with an HSS guitar and refused to give up on actives. For me, when I want an active humbucker or more-humbucker-like tone I will either go passive and use Hot Rails/Cool Rails or I'll change the guitar's routing/pickguard to simply take a full active humbucker. In other words, I only use an active single coil-size pickup when I want a normal single coil-type tone (but I need to stay active, e.g. for a bridge humbucker), which the Blackouts didn't do. They lack the sharp attack of a normal single coil tone and the mids are cranked up so much they make P-90s sound hollow by comparison.
Conversely, EMG's SA, SAV and SLV all sound like varieties of normal single coil. The SAV has the EQ and response of a common A5 Strat pickup; the SA calms down the pick attack a little; the SLV adds a slight overwound flavour, for me making it like the bridge-specific version of the SAV. I prefer the 'X' variations since those have a more dynamic response (i.e. a more modern, power-efficient preamp, like Blackouts have) without needing to find space for 18v. I've not yet tried their newer Crossroads or Maverick pickups but given they're mechanically similar to the SAV but with an even calmer and more dynamic preamp, I have no reason to doubt the claims that they're even more like a common passive Strat pickup.
I don't like the S myself since the extra compression and attack of the ceramic magnet is something I don't like in single coils (also my issue with the ceramic-powered SD Hot Stack Strat vs the A5-powered Hot Stack for Tele), since the single coil tone already has sharp attack anyway. The S might be great for funk (Prince liked 'em enough) but that's not my wheelhouse.
While we're on the subject I'll also add that the EMG Tele pickups (especially the alnico and X versions) are phenomenal, easily my favourite Tele neck single coil and second-favourite bridge (behind the SD Hot Stack). Anybody who thinks either EMG or active pickups in general automatically means high-output metal should go try those. You've never heard a cleaner, twangier Tele bridge or a more bell-like Tele neck.
I like the standard Blackout humbuckers and the Jeff Loomis model, but when it comes to active single coils, SD have a lot to learn from EMG still. They really need to catch up and do some splittable actives, too. (If SD would like to make a splittable/dual-mode JL with white covers and concealed poles, I'd be all over that...)
