Propagating tomatoes

I did a little reading on propagating tomatoes, I didn't think about it to much until I started planting my seeds last week.  I have that amazing little tomato plant from last year that is still producing fruit so I thought I would propagate it.  I pinched off some suckers and planted one in soil using cinnamon as a routing agent and two I just placed in water.  From YouTube I found a video that said to try both ways and this guy didn't have much luck putting the cutting directly into soil, he said to let it route in water first.  So I'm trying both ways and I'll see which way works best, so far both ways seem to be working.  I will let you know in a week.
