The advantage to full comp vs. skip on a saw as powerful as the 394 is not really for cutting speed, but for time spent sharpening. If, in your opinion, you are spending too much time filing because of dulling you chain often, then going to skip with its approximately 14 or so cutters per side instead of 21 or so on the full comp, will get you back up bucking quicker.
There are tradeoffs, of course. Filing to can be a welcome break from bucking, or it can be a source of anxiety, such as, "I'm burning daylight sharpening when I 'should' be cutting". You'd have to make that call.
When I was busheling as a timber feller, I'd often resent having to stop production to touch up my chain. At the same time, I really enjoyed the few minutes of quiet. The camp robber jays would fly up close to see if I was going to offer them some goodies. The pileated woodpeckers might start hammering a snag, or vocally complaining that I was close to their nest. I actually preferred full comp .404 on 30" bars my hopped up 288s rather than skip as I found zipping through limbs was quicker with the full comp. The 228s had plenty of power to pull 30" full comp chisel for felling/bucking in our timber-various firs (Doug, grand, subalpine), Englemann spruce, P pine, lodgepole, others.
