I've made the trip from Atlanta to the Sierra a half dozen times in the past few years, and another half dozen to Death Valley. I definitely prefer going through Vegas (cheap rental cars generally), versus L.A. It's about the same distance overall driving to Lone Pine from either Vegas or L.A., but I find it's quicker and easier going through Vegas.
There's also a shortcut from Vegas to DV that can knock off 45 minutes or so from the traditional route. Take Hwy 160 west (known as Blue Diamond Rd in Vegas) to Pahrump. Eat, drink, buy supplies in Pahrump (Super Wal-Mart recommended for supplies). Continue almost to the end of the business district on 160 and turn left on Bell Vista Rd. This will take you into Cali, where it re-names to State Line Rd, and dead ends right in front of the Old Opera House. A quick right, then a quick left on Hwy 190 has you headed to Furnace Freek, and ultimately Lone Pine.
The beauty of this route is that there is almost no traffic most of the drive. You also have eating/drinking options in DV at Furnace Creek, Stovepipe Wells and Panamint Springs. Do not buy gas in the park, as it runs about $1.00 more than Cali prices outside the park. Top off in Pahrump. You're going to drive through desert to get to LP no matter what - you might as well go through the meanest, baddest one in the world and enjoy it.
