I just got back from a week in Sequoia/Kings Canyon.
I'm a fan of FalconGuides. The problem with FalconGuides is that they try to be everything to everyone. They include many more hikes, but several of them are "shuttle hikes," which require traveling with non-hikers or using multiple cars. If you're a fan of the shuttle hike, stay with Falcon. Then again, I doubt we will ever see the publication of a trail guide devoted to shuttle hikes. "Great Shuttle Hikes of the Rocky Mountains"? Don't look for it on Amazon!
Anyway, author Stone sticks to hikes that can be done by day hikers. No 45-mile, 9-day pack trips. Again, if that's what you're hoping for, Falcon is your guide. But if you're looking for a nice walk in the wilderness, Stone's got that covered. And there are a number of 6-mile or longer hikes. I hiked to Mist Falls (9 miles round trip).
That said, this volume is in serious need of an update. The General Sherman Tree area has been completely redesigned and now requires a significant walk. The Congress Trail is also farther from easy access than it once was. And the Kings Canyon entrance station has been moved away from a "dangerous tree" into the Big Stump parking lot. So for now, there's no parking for the Big Stump, Hitchcock Meadows, Viola Falls trails. Stone might also consider a description of the trail to Crystal Caves.
This is the book I took on the trail. (The FalconGuide was used, but it stayed at the lodge.)
