Manual trans help: Cable or Hydraulic

[strtcar]

I'm totally new to manual transmissions always had auto. Going to do a T5 swap into my 67 mustang, currently its a C4 auto. So i've been reading online lots of people say hydraulic is the way to go, easier clutch engagement, better fit with headers.

Any pros or cons for or against hydraulic, price seems about double, 250 vs 500, but if it will fit and make things easier not a big price to pay relativity speaking.
