The problem with any comparison such as this is to decide what criteria you use to define "best".
The way i have looked at it is that the Isuzu engine was fitted to both the County and the Stage 1 Series 3. So there is no engine difference.
From an operational point of view, the coils have it all over the leaf springs, with a better ride and better articulation, and better axle location and torque reaction. The only drawback is that the shockers have to work harder with coils, and the steering geometry is a bit compromised.
As far as driveability goes, all County trim 110s had power steering (not fitted to all 110s) and this was not available on the Stage 1. Turning circle is better on the 110 as well, mainly because of the wider track. Drive train is the same on both.
So I conclude that by any measure, the County beats the Stage 1.
Now consider County vs Defender Tdi. Here the result is less clearcut, partly because they are very similar designs. The main difference is the engine. Here the Tdi engine has the advantages of being both lighter and more powerful. As against this the Isuzu is more durable and has perhaps better low down torque, plus no turbo lag.
I can't come to any definite conclusion based on the engine, so let's look at other differences. models from 1987 on had thicker doors, which probably rattle less, but lose elbow room. Perhaps more important is that later Defenders used weaker CV joints. Looking at gearboxes - early Countys used the almost indestructible LT95, but only four speeds. The other key difference is drum vs disc rear brakes fitted from about 1992. Discs are superior,but the difference is not all that significant.
All in all, I find little to choose between the County and Tdi Defender, but picked the County because that is what I have.
