When to pick keras

You need the specific strengths: analyzing datasets and training models
You're already in the data ecosystem and want consistency
Your workflow is heavily analyzing datasets-focused
You prefer a focused tool over a generalist one

When to pick tensorflow

You want a different angle on data (vs data)
You need features keras doesn't have
Pricing or licensing model fits your situation better
You want more flexibility in how you analyzing datasets

Try both

Most tools in this space have free tiers or trials. The fastest way to decide is to run a real task on both and compare. Time-box it to 2 hours — past that, you're overthinking.
