should I use a net extender ac750 or mesh extender ex7000?

I have a barn that is 100 feet from my house. I have my AC1900 c7000 cable modem router in my home but I have a underground cat 6 line going into the barn. I am not sure what I should put in the barn that will give me the best connection to the house router. Any suggestions?

I think I have the option of a AC 750 extender or a mesh extender. I like the concept of a mesh estender if that works with my current AC1900 router.

Any help will be greatly appreciated!
