Comparing manual trans options - variables other than gear ratios?

Gear ratios and desired engine power output is usually the biggest things.
If you just had a /6 then a t5 might be a really good option because it's really lightweight and has good gears for modern cruising along with good part availability. If you wanted any real mopar v8 you might overpower a t5 really quickly.
An 833 with a 1:1 4th gear is pretty darn stout but they can be heavy with cast iron case and in general don't like modern freeway speeds (if you plan on driving on the freeway)
An 833 OD can cruise better on the freeway but has long gears with a big rpm drop between each gear so they are really not meant for high performance applications but can be good in a cruiser.
The passion 833 5 speed always sounded cool to me but I constantly hear people complain about having to wait FOREVER for part availability.
All the other T_ _ _ transmissions listed are pretty straightforward with listing their ideal power output capacity.
Past all that, I have never heard of any of the listed transmissions being "unreliable" when used in their proper power capacity
