It helps too that althought some parts are getting scarce it seems, things like coil-overs and other aftermarket stuff to bring the experience into the 20th century (hopefully) are still begin made. I haven't made a decision though between the E36 and E24, but am leaning heavily towards the E24. The only thing I know for sure is that it will have an M62 in it, and it will be British Racing Green.
Luminums tells me that the M62 will go right in, although its tight. He did end up dropping the subframe a bit with spacers, which I don't know if it is for pan clearance, or hood clearance. He's going to send me some pics and more detailed info on his swap experience. Finding a (mostly) rust free car that isn't crazy money could be the long pole in the tent. The OBD2 motor in the E24 worries me a bit, but mostly because this is one area (coding) that I know very little about right now. I've got to think smart guys like DudMD can sort pretty much anything out. For his part, Luminus runs his M62 on a stand-alone ECU I think.

E24 will be harder in some ways, easier in others - the good thing about that swap is that the E32 is very similar, so a lot of E32 parts can be utilized where required. I think you'll end up needing to do things like the remote mount brake booster, but the physical fitment of the engine itself will be a little easier than on the E36.
I'm not a big fan of dropping the subframe because it affects the suspension geometry. This is typically done for sump clearance, on some models people will just modify the sump slightly to let it fit over the subframe without the spacers.
Please share a link once you start either swap - I'd like to follow along

I want to keep the tight handling of the I6 with the steering rack, better suspension and lighter subframe and other bits.
I also know of someone with an N62 4.8 making 400
wheel horsepower that revs to 7000rpm using S65 headers and a standalone DME. He had it dynoed at 450whp when pushed to 7500rpm but bumped it down for reliability reasons as it is a track car.
I am fairly confident that with S65 headers and a proper tune an N62 on stock DME will make at least as much HP as an S62's 394 crank hp and certainly with more torque. My current 4.8 build will be making ~370hp and ~515n-m torque (S62 makes 500N-m) on the stock 4.8 headers.
This way it will be the best of both worlds - E39 I6 handling with M5 performance.
