Pros and Cons of manual & electric winches

The pros and cons are the following:

Advantages for manual winches:
The pros for using these hand winches is that they are strong, well built, and versatile. There is no installation required and almost nothing can go wrong throughout its lifetime. Also it has little and in some cases no maintenance required. Another advantage of a manual winch is that it is much cheaper than an electric winch

Disadvantages for manual winches:
From research the only cons that I can find these hand pulling winches is that they are heavy and that manual labour is required in order for the load to be lifted.

Advantages of electrical powered winches:
An electric winch is permanently mounted and ready to go all the time.An electric winch requires a lot less effort to use and is a lot quicker too. Having an electrical winch is probably best for this projects situation. Manual labour would take a lot longer to lift up 1 tonne at a time.

Disadvantages of electrical powered winches:
The disadvantage of having an electrical winch is that it can get very expensive. First of all buying one that suits your needs. The heavier the load, the more expensive the winch would get. And maintaining the winch can be costly too. Unlike a manual winch, parts for an electrical winch are expensive.
