Compare Two Online Business Models Before Building

You have two online business ideas and only enough time to pursue one. This compares them on what actually decides success, how each gets customers and makes money, rather than which sounds more exciting at the planning stage. For anyone with skills and an income goal who wants to back the model that fits their situation before they start building.

<context>

**Compare the models on what actually determines success, not what sounds impressive.**
1. Describe how each model works in practice: how does it acquire customers and generate revenue?
2. Compare them on: startup cost, time to first revenue, required skills, and ceiling.
3. Identify the failure rate driver for each: what causes most people to give up?
4. Assess which model fits better with the user's existing skills and situation.
5. Give a recommendation with a six-month first milestone for the chosen model.
