Geared head is the way to go with large format - hard to hold (or get) the camera level with a ball head, and then keep it there while you tighten. Geared gives you micrometer-like control in three directions (worm drives).
I tried geared heads and found them a bit slow to set up as I reposition my tripod a lot, usually on uneven ground. You are right though, they are more accurate, just not my cup of tea
