Just got one of those myself a few weeks ago (2003.5) and love it!
Based upon your choices I think either would do fine, both are highly thought of dinos. I think the Penzoil bottles are more attractive, however.
I just changed my break in oil at 900 miles and filled it with 10W30, and it starts quieter now. Cali winters are mild.
The oil filter, however, is the tiniest one on the market I think. I just don't think its up to the task of an extended drain without a filter change midway... but with dino that doesn't appear to be what's on your mind.
Welcome to the MP5 club! More fun to drive than my 03 Maxima!
