One removes material fast, the other removes it precisely.
Verdict
An angle grinder is a bulk material removal and cutting tool: it cuts rebar, grinds welds and slices tile. A die grinder is a precision tool for porting, deburring and detail work in tight spaces. Buy the angle grinder first, since it does the jobs that stop a project; add the die grinder when you need finesse.

You are cutting metal, cleaning up welds, removing rust or grinding down anything at speed. It is the tool that makes metalwork possible in a home shop, and with the right wheel it also cuts tile and masonry.

You are working inside a space too tight for a 4-1/2 inch wheel, or you need controlled removal rather than fast removal. Deburring, cleaning up internal corners and shaping small parts are all die grinder work.

The angle grinder, decisively. Wheels can shatter at high rpm and it throws sparks a long way. Always use the guard, a face shield, and let the tool reach full speed before contact.
With a small cut-off wheel it will part thin stock, but it is slow and not what the tool is for. Use the angle grinder for anything you would call cutting.
For grinding, corded still makes sense: sustained high load drains batteries quickly and grinding is exactly that. Cordless is convenient for short cuts away from power.
