The above mini-description is a pretty good overview of Freelander 'all terrain' setup. In many ways with 4x4 vehicles you're talking limits rather than capabilities and Freelander's main limit is lack of a low-range . This is offset a little by a quite low geared 1st gear - but it is definitely not low-1st. Ground clearance is not fantastic compared to the 'bigger' Landies, but can be improved with a lift, or even spring changes - it does have good arrival/departure angles though.
There are basic off road modifications available - such as lift, springs, some under body protection - but there's not the large choices of air lockers, roll cages etc found on others (I don't think anyway).
So, for green lanes, I'm sure Freelander is more than capable enough and would be a great vehicle to drive them in. If you want to go rock climbing, then not a suitable truck.
The viscous coupling on an F1 is an awesome bit of kit - on and off tarmac. When you need it, as said, its like automatically going into diff lock on the bigger Landies - similar to the viscous center diffs on RR Classic/P38. The Haldex in an F2 in theory should provide the similar capability - but I've never driven one.
Freelander are also economical, reliable and in F1 parts are dirt cheap, readily available and they are easy-as to work on. Compared to the bigger Landies, I've found everything is so much lighter and less seized solid - which makes working on them much more pleasurable.
There are lots more 'electronics' on an F2. In theory, it should make diagnosing faults easier, but in practice I'm sure the added complexity of the electronics often makes it less so and there is more to go wrong and some of those parts are expensive to replace. For example the "steering lock" is electronic and does create problems, sometimes difficult to diagnose - and you simply do not have this issue with an F1. So comparing F1 to F2 is a bit like comparing a D1/D2 to a D3 in this respect. Probably not quite so drastically different as a Defender to a D6
