I'm not that fussed about the tip configuration. I've been cut in-pocket by both, worse by tip down though.
Generally I prefer tip up on smaller knives as it is easier for me to open as I draw from the pocket. Larger knives (> 3.5 in blades), I prefer tip down for the same reason provided they have a decent detent / blade retention.
Having said that, if I like the rest of the knife, the clip position (or lack of clip) isn't going to stop me from carrying it, using it and enjoying it.
