Having Amazon on your resume would be good but you would be sacrificing a lot for that tag only.
Pros (Amazon) - Amazon Tag, Cloud experience (depending on your team), working with a smart set of folks.
Cons(Amazon)- Pip, Night shift, WLB issues, constant pressure, promos are tough. If you plan on moving to a dev role, it'll be next to impossible to get an internal transfer and even if you do, it could be a hire to fire scenario, Salary isn't a lot different from Deloitte, Role is cloud support which will be putting you into entirely support oriented profile.
Pros(Deloitte) - Good company, good wlb(know a few people from the company) , Consultant is a good role and gives you chances to be open for better opportunities in different companies, being a py dev, you'd be right at home in this role, no night shifts.
Cons( Deloitte) - not as big as Amazon Tag, pip might be there but not as bad as Amazon.
You should decide based on where you want to be in your career. Pay and all are pretty similar. Unless Amazon is paying you 1.5x more than what Deloitte is paying you, I don't see any benefit in willingly diving into a hellhole of pip and toxic culture
Fyi - I'm an ex- amazonian .
