There's some discussion at
PG&E customers. What do you spend/mo to charge your car? and other threads in the
California sub-forum. Another recent thread is
PG&E Rate Schedules: "Home Charging" (EV2-A) Goes Live vs. Others — but that thread focuses on solar plus storage.
The short answer is that it depends on your usage and how much you can shift off-peak. You can try to calculate that. There's a PG&E online rate calculator, but it'll look at your past usage, pre-EV. It might be more accurate to simply use the numbers from your last bill.
For me, the EV rate works out best. But I'm on EV-A in an all-electric house with no air conditioning, and I have west-facing solar with NEM2: factors like those can change the picture quite a bit. You'd probably be signing up for EV2-A, not EV-A.
What's best for you will probably come down to EV charging off-peak vs needing to run air conditioning or other major appliances on peak.
