The difference is I can avoid most of that crap when I have to write performance sensitive code, I cannot avoid a slow system without dropping down to the hardware.

Slow is very relative here, the performance penalties are on the order of 5 to 10% or so in absolute throughput terms, latency is usually much better in a microkernel based system because it can use the cores more effectively and even quite a bit of the message passing overhead can be caught as long as you stay on the same physical machine by using the paging mechanism.
