Not my experience at all. Centralised load balancer are simple, easy to maintain, and just works.

My rule of thumb is to always always always avoid distributed computations as much as possible. Trying to avoid a “single point of failure” always in my experience leads to more complex failure scenarios, making your system more likely to fail in hard to fix ways.
