No none of these are "too good"
The ED is a basic eliptical - it will track high frequencies better, due to the narrower side/horizontal contact patch (so it can get into vinyl corrugations that are closer together ie: high frequencies) - because it tracks them better (mistracks less often), it causes less damage - but (swings and roundabouts) it has a smaller total surface area of contact - and therefore applies greater pressure/wear... estimated life at optimal performance is around 200 hrs (after which distortion levels increase... lifetime before it causes damage to the vinyl is much longer)
The VL is a basic line contact needle - it is one of multiple names for this type of needle shape (HE/HyperEliptical, Line Contact, Vivid Line, etc...) - contact patch is vertically extended, and horizontally narrow - this allows it to track the high frequencies while also have substantial surface area to spread the tracking force over, reducing wear to the needle as well as the vinyl - estimated life at optimal performance is probably circa 400hrs.
The SAS is an extreme line contact design, it is both narrower horizontally than the VL (better High Frequency tracking) and typically substantially longer vertically than the VL/HE/LC types - this results in further reduced wear on both needle and vinyl - typically 500hrs+ at optimal performance (measured as point at which distortion starts to rise.... Jico has an article describing how they measured this and compared their various stylus types)
Base stylus life can further be extended by meticulous vinyl cleaning, and vinyl lubrication (yes some of the treatments are lubricants as well).
Many of us have run extreme line contacts types for 2000hrs without perceptible issues.
The other thing to consider, is that the ED, and VL are an aluminium cantilever - relatively heavy, where the SAS is a Boron cantilever, which will have lower effective mass - lower mass = better tracking... and all mistracking involves increased wear to the vinyl (in addition to increased distortion, etc...)
Those people who complain of sibilance on their records, are frequently identifying mistracking... which commony be caused by cartridge/stylus compliance mismatch with the arm mass....
This is where you need to be careful - the Jico SAS N91 is a high compliance needle with optimal VTF of circa 1.3g to 1.4g

Assuming your arm is around 12g - you should be ok with the SAS - but you should try to get as low a mass headshell as possible.

Basically the Shure M91 cartridge was a high compliance design, from the years when the ultimate performance was being achieved by high compliance cartridges with low mass arms...
Your best arm / cartridge-stylus match would probably be something around 1.6 to 1.7g - the Shure is in the sub 1.5g vtf category.
It's a great little cartridge - and one for which a wide range of needles are available ! - you can also get "Fat" needles for tracking early 78rpm records
Sadly shure got out of the cartridge business - but they were one of the biggest manufacturers, and there are HEAPS of them out there, with good market support to keep them running! (as can be seen by the stylus options you have!)
