When should I create sketch pattern and when should I use feature pattern in Solid works?

Dear Solid works users,

I generally use ptc creo but now interested to use solidworks too. In solid works sketch, there is an option called sketch linear and circular pattern. When should I use it?

Also there is an option called pattern in solid part modeling. There are also linear and circular pattern option along with many other pattern options . When should I use it?

Any ideas, suggestions, discussions regarding this will be helpful.

With regards,

Soumya
