Both motors have their own advantages...I nearly bought a 300tdi disco a couple of weeks a go as it was cheap and they do make a really good tow car for dragging stuff around. Being honest I would sooner tow an ifor with a 4x4 on it with a disco than a lwb fronty or the chevyfing...they just feel so much better at doing the job.
For offroading the 90 is a formidable beast, with aproach and departure angles from standard that put fronties to shame, but they are a bit fragile, and corrode well.
Later ones are tougher but carry a huge price.
For offroading discos are ok but are designed as mainly a road car like the fronty. They have silly running boards that get in the way, monsterous towbars that will ground out on a catseye and silly front valence that is lower than the front bumper on a fronty.
Modified on a limited budget, like a set of tyres, a modest lift (BL in the case of a fronty and TB tweak, hangers, or coil spacers), and removing the "get in the way" bits both the disco and fronty would be reasonably competant off road, both with advantages/disadvantages.
The discos articulation is great, but a good fronty driver could negotiate the same obstacles...disco drivetrain can be a bit weak on earlier ones without the 24spline axles, but so can fronty front diffs.
The answer is that offroading ability comes down to driver and machine...
...the driver must be competant and have an understanding of how the vehicle works in order to get the best from it...
...the driver must understand the limitations of the machine and be able to read obstacles and apply the vehicle in a way that will be successful..
...the driver must be able to feel what the vehicle is doing and be able to determine the correct reaction neccesary as the vehicle progresses
...the driver must know the limitations of the components in the drivetrain and drive so as to keep the strains applied within the tolerance of these parts...
...by the driver making stuff and trying one mod at a time really helps build the understanding of the vehicle as it evolves and gives a better unstanding of what changes on the vehicle on every step and how these changes impact on performance.
I guess we have an advantage here as mods for our marque are not so readily available, so mods tend to be done one at a time with driving time in between where the mods performance is assessed,
whereas I guess a lot of the disco lads will phone up craddocks, order a whole load of stuff and bolt it all on in one go.
As for driftys initial point about what could you build for the price of a modded 90....you could build something awesome!!
BUT
Really it wouldnt be completely fronty anymore,
but only in the same way as a tricked up 90 has only body/frame/gearbox/engine that were as solihull intended...everything else would be sourced from other manufacturers.
If you had a budget of say 5k you could...
Buy a 2.8 swb
fit TF case doubler for supa low gears
Replace axles with Landcruiser or patrol items with lockers
tune engine with bigger intercooler.
4 link the front and rear suspension with coiler overs
External rollcage
Couple of inch BL so you could run 35's or 37's
Front and rear winches
and still have a little bit of change! This is assuming that you do most of the work yourself mind...
This spec would perform as well (if not better) and be as tough (if not tougher) as any tricked 90 and would be really different.
Watch this space though as this is what is happening to my chevy and the yella fronterror (with a 350cu in V8 chevy lump as well!)
but mods will be done in stages so as to gauge each improvement and avoid having it off the road with no playing for long lengths of time.
Chevy is getting nissan patrol axles with lockers, remote patrol tf case as doubler for 2wd hi 2wd low,4wd hi,4wd low, 4wd double low and neutral tf box options!
Might fit fiddle brakes to rear also, but front is getting 4 linked first,and 2nd tf case installed, with nissan rear axle simply SOA'd on the chevy rear leafs, then the rear will be 4 linked a later date. If I 4linked it all in one go and then it drove like poo, I wouldnt know where to start in terms of sorting it, but one step at a time will make adjustment/correction possible. Gonna also build another external cage for it a bit like the one of the fronterror.Will do loads of pickies of the build like the SOA thread!!
The lessons learned on the chevy will then be applied to the fronterror, but that is getting a different powerplant for huge HP and V8 grumble!
