You didn't give us a lot of data to go on (size of home and its location), miles driven, AC usage, other heavy electric consumers.
It sounds like you don't have PV, so switching to TOU-5 from TOU-2 is easy - TOU-5 will be cheaper. But with MB rates, you will have to analyze your usage and your ability (and willingness) to shift loads. Based on your $1100 bill, you are probably using around 3200 kWh/month - a very high usage for San Diego area. That would likely put you over 400% baseline on normal DR rates. It will put you right around 400% on MB DR rates. If you do no other load shifting other than EV charging and the pool pump (hopefully variable speed), I still think you will SLIGHTLY come out ahead on TOU-5 MB rates. Assuming around 1000 kWh super off peak/month.
Switching rates won't magically cause your bill to drop from $1100 to $200/mo - the other plans may drop you to $900 - if you really want to reduce your bill, you are going to need to take control of your usage and find out where you can save. The EVs are probably not contributing to as much as your bill as you may think (2000 miles a month at 3.7 miles/kWh would only cost you $124) You need to look at other consumers: AC use, old refrigerator (or multiple refrigerator/freezers), incandescent bulbs, cable/satellite DVRs on 24hrs/day, computers on 24hrs/day, single speed pool pump, pool heat pump and the basics - leaving lights on, TV on all the time, etc. Hopefully you have gas available and aren't heating water with electricity.
For reference our June bill without solar would have been $250 - only one EV at 1000 miles/month and a pool, 2900 sq ft, 1980s construction in east county. June was a cooler month though, our July bill would be $385 where we ran the AC a lot more. We load shift what we can to super off peak - pool pump/SWG, dishwasher, EV charging and we are well aware that when we turn on a light switch we are making a purchasing decision. Our annual usage is 10,500 kWh and it didn't take much effort - and I estimate I can use over 50% of that on super off peak when I switch to TOU-5.
Also, don't knee jerk into getting PV, look to get your usage under control first (then if you desire to have PV which is not as beneficial as it once was, the system can be a lot smaller).
