I am by no means an expert, and I had questions about this at first too, and lot's of see-sawing back and forth. But in the end, I decided to go with what the prototype does on their routes. Power switches on mainline sidings, crossovers, and junctions. Manual switches on industrial branchlines, in the yards, and on the and spurs - anywhere you may be shunting cars.
I started out my route with all switches in manual. But, when I ran a standard scenario, I found it quite unrealistic to have to throw a switch to go into a siding, when in real life that is controlled by Dispatch. From what i've heard on the scanner, explicit permission has to be given from Dispatch in advance in order to hand operate a powered switch. However, doing it this way does have it's drawbacks. As was said above, services will lock a manual switch in front of you unless you have your priorities straight. And, if your player train needs to go through a crossover to get to the other track to get to an industry, you will not be able to throw the automatic switch in standard scenario.
In the end, you basically have to decided what is best for your route and the scenarios you will be writing. However, I will say that since installing the auto-switches, I haven't ran into any "checkmate" situations that could not be solved with a few well placed markers and some ingenuity.
