Good shot, Norm, it clearly shows the difference you can get in lighting.
As for me, my layout is small and in a single room, so I have a LED overhead mount. The 'cans' are small but they cover a lot of area. I only have one small spot that isn't covered from this mount:
I love the lighting effects I get from it, as it looks just about right for mid day in the summer time, when my layout takes place. I also gives very strong shadows, just as the sun does. I've never liked 'track' or diffused lighting that many in the hobby like, as they often kill shadows you'd see in real life.
As for interior structure lights, I model the 1940s and pure white LEDs don't look right for that timeframe. I use Woodland Scenics ones with the yellow tint to light the insides of my structures. To my eye, they look great for either incandescent lights with shades or lantern lighting.
