Having shot myself in the past with a 10mm rectilinear lens (Sigma 10-20mm) and a 10mm fisheye (Tokina 10-17mm) I can tell you that the difference in hfov is very noticeable. It's basically the difference between 2 rows of 8 shots, nadir, zenith (so 18 shots total) and 6 shots around, nadir, zenith (maybe two, I don't remember right now) so 8 oder 9 shots in total. You can actually enter the numbers in hugin to get an estimate. Assuming crop factor 2 9 mm rectilinear yields 90° hfov while 8 mm circular fisheye yields about 130° hfov. Back to the original question: For me the step from a wide angle rectilinear to a fisheye was very well worth doing. The noticable but bearable quality difference is outweighted by the much easier stitching with the lower number of shots, especially so for 360x180s.
