I have an 820. I haven't played with or even seen an ATIV but I'll pass along my thoughts on the 820.
I went into a store expecting to buy a 920 or an 8X but walked out with the 820.
-The in-hand feel of the 820 was my favorite. The 8x was too dainty, the 920 was too bulky. The 820 was just right.
-The screen on the 820, while low resolution was a big draw for me. I love the deep blacks of AMOLED and unlike most AMOLED screens the colors look accurate to me.
-I prefer the 16:10 aspect ratio of the Lumia devices over the 16:9 on the 8X. Purely personal preference.
-I like having the micro-SD and removable battery on the 820. My biggest complaint initially with the 820 was that the on-device maps chewed up the on device storage, but Nokia came out with a beta app that allowed me to move the maps to my SD card so I no longer have any issues with storage.
-I'm in the US on AT&T, I'm a fairly light user but at the end of a 16 hour day I'm usually at 60-70% battery. It's not as good as my iphone 4s was, but I'd say it's within about 10-15% of what I got out of that phone. I do occasionally have days where something chews thru the battery, I've always caught this before it left me with a dead phone but it is something that I'm hoping is fixed with GDR2. I don't know if battery life varies from one network to another, so YMMV.
-The camera is better than I'd hoped. I'm not a photo enthusiast, but I do use the camera/camcorder as a practical tool (snapping photos of prices when planning a home improvement project, recording video of an area I can't fit my head into when working on my house/car). It quickly focuses, colors look good, exposure is good. No complaints. It's also handy having a flashlight in my pocket at all times.
-It's a good phone. Yes, I make calls on my phone.
Keep in mind that when I make a decision on something I'm usually pretty darn happy with my decision. So obviously I'm biased
