In the case of the Strat-90s and the Rose Mozsarts they are both great pickups and I would (and most likely will) definitely use more of their pickups.
The Strat 90s actually sound quite similar in voicing to the CP69s but with a lot more punch. Here's a little comparison I did awhile back between my CS69 loaded strat and my Strat90 loaded Benford S-Type. It doesn't really do justice to either guitar but it gives you an idea.
The Luna Sol with the Rose Mozarts is like a whole different guitar now. Of course going from a humbucker to a single coil one would expect a pretty noticable difference but the Mozarts really breather new life into the guitar.
Also the Rose Belle's sound fantastic based off the clips I've heard and are easily worth the $90 price.
