  We prove optimal estimates of the Bergman and Szeg\H{o} kernels on the
diagonal, and the Bergman metric near the boundary of bounded smooth
generalized decoupled pseudoconvex domains in $\mathbb{C}^n$. The generalized
decoupled domains we consider allow the following possibilities: (a) complex
tangential directions need not be decoupled separately, and (b) boundary points
could have both finite and infinite type directions.
