Inland vs Hurst shifter...what makes Hurst better?

Inland 4spd. vs Hurst Competition 4spd shifter...what makes Hurst better?
This is the second rebuilt tranny I using in the last 5000 miles because the Inland shifter doesn't slide like butter into gears unless I drive her 15 - 20 miles and even then she'll need some force to go into 3rd gear unless I get the rpms up to 3500 and shift. Both trannys did this in 3rd gear. My buddy double checked and we're using the correct fluid weight. He and another buddy suggested I would get better performance from a Hurst shfter vs. my factory Inland shifter in my '66 Barracuda with a mild 273 build up (about 285 - 300hp, 4.10 rear, console sifter) If I swap over to a HUrst what do I need...Hurst shifter, install kit, rods or is just a shifter swap out I can use the same rods. Any insight, part numbers is appreciated.
