Looking for cooling fan recommendations

To Lasko owners.

I am in the process of getting one of the Lasko fancy powerful fans.

Now, my problem is I have no idea which one is the one most people recommend.

The second highest setting has less air flow than lower setting of the first.

Do i need/want the air flow from the first or the second one will be just fine?
Currently i use 2 of these (one front right and one back left)

During summer, i set my ac to 70 during early morning wo.
