High tensile vs Barb wire

It seems many of you are big fans of high tensile vs barb wire. What are pros and cons of high tensile?

I need to fence about 3/4 mile of permanent perimeter fencing this spring. I am open to changing away from barb wire. My initial plan is 5 strands of barb wire on 6 foot t posts 12 feet on center.

What goes into high tensile? 6.5 foot pounded posts 30 ft on center? What size wire?

Pros to barb wire:

I have done enough to kinda know what I am doing for here. I can easily price it and complete myself with equipment I have. No worry about electric.

Ready to hear all the cons and pros of high tensile.

Also, are hot wires required on high tensile?

Thanks.
