Personally, I can't see any reason to opt for a J, unless it's significantly
cheaper (and even then I'd go for one of Herman's conversions instead). The
A-type gives you an extra gear and instant shifts, both of which I found
very useful in my 59 TR3A, particularly when driving hard on twisty roads
(which is my favorite way to enjoy the car). The J shifts quite leisurely
by comparison, making it useful only as a 5th gear, IMO.
The J-type is also more trouble to fit to a TR3; you'll have to fabricate a
new rear mount and some people have had to notch the frame rails for
clearance. You'll also have to bang out the transmission tunnel to clear
the larger, later gearbox; since you can't fit a J-type to the original TR3
box.
After having driven the A-type in my TR3 for many years, I rather regret
having opted for a J-type in my Stag; even though I feel it's better able to
handle the higher torque of the V8 and also has a slightly higher OD ratio.
