I mean, the numbers you've posted are all fine. The LA job would absolutely put you at a lower savings rate simply because of the higher cost of living.
This is your first post on the forum, but looks like you're pretty familiar with the general concepts of of the site, so the real answer does not lie in the decision between job "A" or "B" or "C" -> "X". Instead, this is the question you need to both ask and answer: what is most important to you?
Do you know what you're aiming for? FI? FU money? ER?.
What's your timeline? Do you want one or all of those things in 5, 8, 10, 15 years?
Do you want to be married? Kids? Travel? Own property?
What's your current savings rate?
Maybe you've already gathered this. but a lot of people miss this nuance - MMM and frugality are not actually about trying to retire as fast as possible. It's all about building the life that brings you, personally, the most happiness/fulfillment/contentment/excitement (in a morally, socially, and environmentally friendly way).
Are you TRULY miserable where you are right now? Do you know for a FACT that you'll be happier living in LA & shifting careers? If you don't then the first thing you really should do is try and find happiness/etc. where you currently are. I'm not trying to tell you that your current situation is the best you can do, but the grass is always greener until you get to the other side. Maybe you'll find that you hate living and working in LA, or that your new career plan sucks. By trying to see all the good things in your current setup, you get to learn exactly what brings you whatever it is you need.
If you have these questions answered, then you should know exactly what to do. The forum can tell you what's the most frugal thing to do but the forum will never be able to tell you the most fulfilling thing to do.
