These companies operate in different sectors (BEEM (Energy) and AMRC (Industrials) and CBAT (Industrials) and NRGV (Utilities) and EVGO (Consumer Cyclical)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: BEEM is a small-cap quality compounder stock; AMRC is a small-cap quality compounder stock; CBAT is a small-cap deep-value stock; NRGV is a small-cap high-growth stock; EVGO is a small-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.
