In minix there is a server that restarts other servers when a server
segfaults.  So that increases stability.  As for security, when one
gains access to the TCP/IP server, you can not immediately gain access
to confidential information.

This really depends on the microkernel.  Mach is not easy to maintain,
Tanenbaum claimed minix is easy to understand and to maintain.
Perhaps Shapiro can comment on this, he has a lot of practical
experience maintaining a microkernel.
