I also own both and like the Stilletto better for warm water diving, while the Knighthawk was my workhorse cold water BC. 250 dives with it, no issues except a cracked inflator hose. The pocket issue was discussed above. In warm water and with thinner wetsuits and less weight the Stilletto rocks and packs for travel much easier. The trim pockets are optional and adjustable and I believe can be mounted on the upper band.
