These companies operate in different sectors (POCI (Healthcare) and VIAV (Technology) and LITE (Technology) and COHR (Technology) and CIEN (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: POCI is a small-cap quality compounder stock; VIAV is a mid-cap quality compounder stock; LITE is a mid-cap high-growth stock; COHR is a mid-cap high-growth stock; CIEN 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.
