Two that I am most familiar with are:
Confrontational..
And
Relational
Confrontational, is to me, the door to door cold calling, or Street evangelism... I have done some, but I see better results from Relational.
Relational is building a relationship with someone, then presenting the Gospel. This doesn't have to be a long time.. I have met someone before, and within 5 minutes have shared the Gospel with them... Other times it may take longer...
Growing up, I was taught confrontational, Tuesday evening visitatation, and it was more like a salesman approach to the Gospel.. Many got "saved", but they are not in church now, no signs of fruit in their lives.. but if you talk to them, they will tell you they know they are saved because they remember the one time the preacher came to their house, and prayed the prayer with the preacher...
After I got into ministry, my Area Minister from our denomination gave me a book on Relationship evangelism... and the ones that I led to the Lord this way are in church, and are being fruitful... It is not as many because it takes time... but I feel it is more effective in the long run...
Think of it this way, if each Christian would build a relationship with someone and lead them to the Lord within a yr, the Kingdom would double in size each yr....
And we all know someone who is lost...
And if you don't know someone who is lost, it is time to make new friends.
