Strutters work well earlier in the season. When I am setting up on a field gobbler, I like to use a strutter and a submissive hen. Later in the season when things are winding down, especially later in the day, I will use a jake and hen or a lone hen.
The biggest plus of using a strutter, for me, is visibility. I can make mine spin, this adds movement that the birds pick up on from a long ways off.
