Okay, cool. Well....those somewhat relate to my thoughts when I got mine. Just to add more confusion to your choice...
I decided on the double-cut mostly because I got curious about them from a Jeff McErlane video, and he plays DC 594s (maybe just one of them?). I'm suggestible in at least that way. They did have some single-cuts at the shop, and I barely looked at them. But, I also already owned a LP that I really like. I wasn't specifically looking for a LP replacement...I wanted to support that shop, and I was curious about the 594. I like that it doesn't look exactly like a LP.
SE vs S2 wasn't a thought then...they didn't make SE 594s. Core vs S2 was just about price...my LP is my most expensive guitar, and I didn't want to spend more than that at the time. I'd still buy an S2 over an SE because most of the guitar is American, and that matters to me at least some. I know the internet is convinced that the guitar doesn't matter to its sound, but...meh. The other take-away from all those videos is that you can play whatever blows your hair back without worrying about it, and that's one of the things that kinda does it for me (except for my '85 strat, because they were all MIJ then and my Indonesian acoustic...because it was cheap and I don't play acoustic very often).
The electronics in the S2s are Korean, IIRC. But...I also changed most of them and planned to before I had played a 594...as long as it's not a valuable vintage guitar, I don't mind messing with electronics. You can always put it back. I've never been a fan of PRS pickups, however small the difference is. I know it's not supposed to matter, but I've always been happier with humbuckers that can't coil split (as well as unpotted ones), and I was going to put RS SuperPots in it anyway because I just like them. So, I have the Korean switch and Jack...some random PIO caps I had lying around, SD Seth Lovers, and the RS pots. I actually think I lost the PRS pickups...at least, I can't find them now. Whatever. The Seth Lovers....I honestly don't even know if they actually sound different...I never compared them. They're made on one of the winders that Gibson owned in the 50s...there's a non-zero chance that my pickups were made on the same machine as the ones in the Beano Burst or Page's #1 or Principal Skinner or Greeny or some other famous burst...and that alone is enough "vibe" for me.
