Which cell tower is better to point at

Question

I live in Ireland, and plan to live in a remote area. The problem is the broadband available through physical means is non-existent (1Mb). With that in mind I've decided to give mobile broadband a try, and set up an antenna to point to the cell tower. My question is which tower would be my best shot:

The "three" provider is the closest according to cellmapper:

but, meteor has a high gain tower a bit further away to the north west:

If anyone has a way of figuring out the range on these towers based on the data on cellmapper, please do share how to figure that out as well!

Answer 1

The answer was the tower to the North. Even though North West was still accessible, the signal was not as strong, I guess in these situations waving the antenna around is always your best option.
