These companies operate in different sectors (AES (Utilities) and VST (Utilities) and NRG (Utilities) and GEN (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: AES is a mid-cap deep-value stock; VST is a mid-cap quality compounder stock; NRG is a mid-cap quality compounder stock; GEN is a mid-cap high-growth stock. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
