When considering options, don't compare options of differing levels of fidelity.
The effort to take a high-level ambiguous solution to increasing levels of fidelity takes significant time and effort… and also likely uncovers more unknown unknowns.
Fidelity increases by an order of magnitude in each of these phases:
A high-level sketch of a solution
A design doc of a plausible solution
A prototype of a plausible solution
A solution working in the real world today
A solution that has worked in the real world for a decade
Each order of magnitude of fidelity requires an order of magnitude of work to accomplish.
Each timestep of work to flesh out has a non-trivial chance of discovering a game-over condition for that solution.
Some abstract ideas sound great, but as you flesh them out they disappear, like a mirage.
Ideas only get less pure as you develop them to higher fidelity.
If you compare one option that is at high-level sketch, it will look pure, clean, and promising, especially compared to a messy, bug-ridden prototype.
But the work to create the extra fidelity in the former will almost certainly make it messy, too.
And worse, the other approach might turn out to be non-viable as you develop it.
Pick the pre-existing thing that is the highest level of fidelity that is a good enough match to your specific problem domain.
