From what I can make out the 5701 is a LSD traditional design.
The 5705 is a Torsion Bias (TB) diff.
Defender & Discovery 1 & Series 3 & Range Rover Truetrac Rear 10 Spline Detroit - DA5705 (jgs4x4.co.uk)
Difference is the LSD uses friction plates (like clutch plates) where as the TB uses mechanical friction to promote the diff locking.
Dont know which is best but I am heading towards TBs for myself, If you look at the Ashcroft site you will find quite a price diff.
Maybe 2 for the price of 1
.
A couple of guys who may have other thoughts @Brown @Turboman

1 is a locker the other a limited slip .... the 701 automatically locks the rear diff (when a wheel is unweighted) giving equal drive to both wheels and the unlocks when it's not needed.
The 705 is the Turetrac Limited Slip Differential that provides a percentage of power to the wheel that is unwieghted (ie spinning) on the axle.
Both are made by Eaton and called the Detroit Locker and Detroit Turetrac.

As said above, one is a locking diff, one is a limited slip diff.
I had a Detroit Locker in the rear of my Ninety, and a Tru Trac limited slip in the front.
If you have a locking diff in the rear axle, you should really have an LSD in the front axle, as the locker in the rear can make steering heavy in it's own.
The Tru Trac LSD is good in the rear axle alone. It gives extra traction, doesn't effect steering much, and is fit and forget, there are no levers, switches, air pumps, or any other gubbins. It does what it says on the tin, and you don't have to take your hands off the steering wheel to activate it.
Quite adequate for green laning on any of the many lanes I have driven.

I don't have firsthand experience of the Detroit units @marjon, but I do have Ashcroft's own-brand units in my axles and transfer box. These were put in in the autumn of 2014 (axles) and at Christmas at the end of 2015 (centre). I've written about them elsewhere. They've been in the axles for just over eight years and have been pretty much a fit and forget experience, though I have changed oil occasionally. No noise, no adjustment needed, nothing. In this winter's snow and ice in Wales I've been very pleased with them. I've just sailed up slopes effortlessly, far beyond the tyre marks of other vehicles that have zig-zagged all over the road and given up. I don't really have a 'technique' as such, just to try to keep the vehicle moving, in the highest gear in which it will do so. I have a non-ABS model so often need to pump the pedal to stop it. It seems to work, because I haven't hit anything yet. The only time it wouldn't go was on a slope of freshly dug clay on which it had been raining all day, and I hitched myself to a conveniently positioned @Remora107. It was just so slick none of the wheels were gripping. Oh, and I embedded it in a swamp on my smallholding once when taking tools and parts to my stranded digger, but that was because the wheels had sunk right in and it was resting on the axles. Fortunately I pulled it out easily with a dumper truck. But aside from these very specific circumstances, it's fine for snow driving and farm tracks.

If general use and driving on fields or green lane is your thing an Ashcroft ATB [ torque bias ] may suit. Have a look at site for more info.

I don't think Ashcroft do a 10 spline, thats just the detroit boys.

I am afraid they are ultra rare and difficult to get hold of , thereby making the cost prohibitive . Brown was extremely fortunate that there happened to be one around when he needed it most .
