Which layout is better for comparison?

There are 2 ways to layout your indicators for comparison between 2 periods. One is to put one top of the other and the other is to put them side by. 

Which one would you choose?

I would choose the first one (compare top and bottom) because I can see the same indicators in the same column. The data source to create this report is also scalable and we can compare more than 2 periods as time goes by.
