I live about 10 minutes from LAX and fly in and out of there often. If you are in relatively good health and like walking, I would walk to the LAX-It lot from terminals 1 to 3 and even 7. To me unless I have just a little carryon, it’s kind of a hassle waiting for the shuttle (even though the are frequent, at peak times they may be full) and lugging your bags on to the shuttle.
Once at the lot there are separate lines for Uber, Lyft and taxi. I usually compare the prices on the apps between Uber and Lyft and just pick the cheapest. Occasionally due to surge pricing they are crazy expensive, in which case I usually do better with a taxi.
