Rate Constant of Overall Reaction vs. RDS

***EDIT: I meant Keq in the title***

As I understand, you cannot use Keq of the overall reaciton to compare speeds.
If not, can we use the Keq of the rate-determining-step to determine and compare speeds?

For example, if:

Reaction 1: Overall Keq = 10, RDS Keq= 5
Reaction 2: Overall Keq = 9, RDS Keq = 6


Can I conclude that reaction 2 is faster?

I am no chemist, but I think that if you knew the K value for the slow-step (RDS) and the concentration of reactants, then we could determine which reaction moves towards completion faster.
