I very much enjoy my SMOK AL85 (Baby Alien) and haven't seen it recommended yet in this thread. I find it to be a very comfortable device and the perfect size. It's very similar to the eLeaf iStick Pico series. The Vaporesso Swag has been on my radar as well lately, but I haven't pulled the trigger yet. Design-wise, it's in a similar vein to the AL85 and Pico.
