This looks very nice, definitely TW, but this one has a little more Afghan influence I think, which makes it a bit stouter. I had a pheno just like this, was quite piney, TW with a hint of pine.
The pheno you had looked to be a Thai leaning one, but in my experience, there isn't a huge amount of variation between them so I will put a fair bit of the difference you are seeing down to different grow styles.
So have ya only kept a cut of the tall pheno you have?
Get you friend to reveg that pheno he has, I think it looks very nice indeed, the extra lil bit of Affie influence has made her stockier and most importantly, stronger stems as she is standing upright and proud, whereas the other phenos all tend to have the floppy-ass stems of the Arcata line.
This is the mother I chose, as you can see it looks like your friends is a slightly more indica pheno as the mother was a little less chunky in the buds and with floppy stems (it's held up by bamboo, hence the dogleg in it). Your friends' has leaves that look very similar just a tad thicker blades, in short, the plant he has is TW with a little more of the Affie influence expressing, this could indeed be the keeper pheno as it will probably retain the TW taste and high but obviously has improved yield and structure as it's shorter, chunkier and stronger than the Arcata wreck.
