Personal preferences,period. Some people like the looks one way or the other, others appreciate the small additional weight a full lug provides while others (like me) don't seem to find much benefit in it.

My personal preference is for the half lug - it looks "right" to me and protects the extractor rod unlike those with no lug at all.

The only full lugs I really like are on the 4" L frames. Like I said, just personal preferences and aesthetics. No doubt you'll get the full gamut of opinions from everyone on their personal preferences.
