Sisal, manila, and Jute are three different materials. The only thing they have in common is long fibers suitable for cordage. Given the very small diameter of jute fibers compares to Sisal or Manila, you can expect it to burn much better.

Sisal and Manila fibers are both stiff, large diameter fibers. Sisal is from the leaves of the Agave Sisalana plant in Central and South America. Manila is from the leaves of the Abaca banana tree of Philippines, Ecuador, and Costa Rica.

Jute is a very soft, small diameter fiber. Jute fiber comes from the stem and outer skin of the jute plant in Asia Minor. It fuzzes up almost like a cotton ball.

I made a length of cable laid (3 cords, each of 3 strands, each of 3 yarns) Jute rope out of garden twine, and it was softer and more supple then nylon rope and as fuzzy as a wool blanket. My Manila ropes were neither soft, supple, or fuzzy. Sisal was even more so.
