How much complexity, data quality, and execution burden each one introduces.
Whether the downstream portfolio behaves differently once the choice is deployed for real.

Short answer

conviction sizing differ from equal weighting and signal and portfolio design solve related but different problems. The practical difference shows up in what each one controls, what evidence it needs, and how it changes the downstream trading rule.

Where the difference shows up

The cleanest comparison asks what each side changes inside the workflow. In signal and portfolio design, that usually means looking at selection logic, sizing rules, turnover, and what kind of evidence the researcher still needs before trusting the result.

How to choose between them

Choose the structure that matches the decision you really need to make, then compare both under the same validation discipline. If one option only wins when the assumptions become unusually generous, that is usually the answer already.
