decider-2b vs laya
Both are decision models. What separates them is licence, architecture, size and whether anyone has checked the numbers. Only one of those is a matter of opinion.

What actually separates them
laya is 4.5 times smaller
421M against 1.9B. At high volume that gap shows up as cost and latency long before it shows up as accuracy, so the question is whether the larger one earns the difference on your decisions.
Neither has been measured by anyone independent
Both are days old and every figure in circulation about either was published by the people who trained it. The table above is what can be checked from repository metadata. Everything else about these two is currently unknown.
