Default Ignition coil - life expectancy?

Do ignition coils degrade or just fail?

I've read some people get over 200,000 miles on them.

With 150,000 miles on a 1999 RX300 and a possible ignition coil failure (error codes 300, 302, 305), I am debating changing the problem coils or all the coils.

Change just the coils that are having problems.

I'm at 174k, and all of my coils are original same with my uncle who's at ~380k miles.
