Will method of automating workers change strategy?

[planetfall]

There are three methods of controlling workers:

1. manual, each move == very, very slow
2. A{utomate} == may do XXX? bad??
3. Shift-A{utomate} == they do not redo improvements.

Does either Automated workers or Automated workers with no redoing of improvements have any effect on strategy??

Thank you for your ideas.

Option 5, of course

I usually manage the workers by hand, occassionally setting one or more of them on special automated assignments, some of which may last the rest of the game:

A - fully automated, Don't use.
Shift-A - like A, except doesn't change previous improvements. Don't use that either.
Shift-I - improve city. Not a bad option for cities that you couldn't care less about, like totally corrupt ones on another continent. Core cities are too important to use this on.
Ctrl-N - trade network. Much to important to use early on. Later on, rarely needed.
Shift-P - clean up pollution. Obviously a good thing, if you have railroads. Use as necessary.
Shift-J - clean up jungle. In mid- to end-game, when the order in which jungles are cleared doesn't matter much, I may set a few workers to do this.
Shift-F - clean up forests. Annoying option. I once spent ages trying to figure out which worker was demolishing my forests on the tundras.
