Which is the best route to take to Oceanside from Phoenix? Either I-10 or I-8? I've taken both routes before but can't remember the pros/cons of each since it's been so long. I HATE driving anywhere near LA area so that's why I'm considering the I-8 route instead.

The mileage and time is probably not significantly different, but wanted to know the terrain and any other major concerns if taking the I-8 route.
