Incorporating in CA or DE as a software agency?

Question is pretty self-explanatory. Just started a no-code dev agency, have stoked clients and want to set up our legal structure right. Context:

Live in : CA
Clients in : Mostly east coast. No CA-based clients so far

I'd assumed I should go with the DE LLC, then register as a foreign agent in CA.

However, I'm also seeing conflicting advice on the grounds of dual franchise tax. In my case, they say I should just register in CA.

Can any software / dev agency founders with a similar context weigh in?
