Backpacking stove and cooking kit

I have read many reviews about backpacking stoves. It becomes confusing at times because it seems that for every good review there is a bad one. 

I'm an old guy that is getting back into backpacking following retirement. The vast majority of my trips will be 2 or 3 nighters/probably no more than 5 to 6 miles per day. 

I suspect I will be using mostly freeze-dried food. I'd like a stove with a cooking kit recommendation. 

I will usually be cooking for just one but would like the flexibility of cooking for two.

Thanks much for your advice.
