IMHO 101 is much more scenic especially along the coast. If you take 101 and depending on where, avoid rush hour (Fri afternoon, Sat mid morning/early afternoon) near LA and Santa Barbara if possible.

You might come across some roadwork near King City on the 101. It's passable but the concrete barriers might be right on or adjacent the lane lines for about 1/2 mile or so. If it's still there you might want to slow down to whatever you're comfortable with.

Ditto on going around San Fran. If you take the 580 bridge going north bound, the booths on the right are a few feet wider. Toll payment info:

North of Myers Flat, the 101 gets a little narrow in a few sections near the Humbolt redwoods where you might want to slow down. It's wide enough for semi's but feels tight as you pass a number of redwood trees near the roadside.

Safe travels!
