Use a 5w30 for normal and even moderately spirited driving. The thicker oil weight is probably only good for all-day track racing and would be too thick for the close clearance engine. Either of the brands would be ok but Redline has the highest group rating and contains Ester as recommended by the owners manual if that's something you're interested in.
