Am I correct in thinking that if you had a choice between USING an LN or a Clifton, that you would choose the Clifton?
Thanks,

Absolutely, without a moments hesitation.
When honed at the same angle, hand forged carbon steel is only 6% less wear resistant than A2 but will take a sharper edge and therefore produce a smoother surface on the wood - one of the main aims of the exercise.
Carbon can also be differentially hardened, so the blade is self damping, air hardening steels can only be through hardened.
With Clifton's extra shaping on the castings, ring testing, careful annealing process and 20% machine feed rate, grey is capable of withstanding quite severe impacts, but unlike ductile it is also rigid - it can't bend - grey cast iron surface plates are manufactured in exactly the same way and for the same reasons.
Ductile was developed for underground pipes, preventing leaks with its ability to deform significantly without rupturing, but if it's bendy it can't also be rigid. Looking at the finish they achieve I doubt if LN run their machines at full chat, but they wouldn't alter the properties of the material if they did.
Clifton also incorporate the milled slot for the frog to ride in from the original bedrock design, so the azimuth of the frog face is always correct. LN mill the bed to full width and the frog just sits on top of it. Minor issue, but if the bloke making it takes his time getting it just right, it's one more thing you'll never need to think about.
The quality and accuracy of ground surfaces is the same, although Clifton don't make a marketing point of working to half the required tolerance, (they probably should).
There are a few points in the marketing literature that draw your attention away from these features, like the number of turns between forward and reverse on the blade advance. Clifton got theirs down to half a turn because enough people grumbled about it, but they could never work out why, if the underside of the lever cap is prepared properly and the thread is lubricated with pencil then the wheel should spin freely between one and the other with a flick of the finger.
The Americans do beautifully finished high precision castings like few others in the world (they even cast their car crankshafts rather than forging them) so as an objet d'art any LN looks absolutely stunning. The meticulous machining and hand craftsmanship that goes into making them is also of an exceptionally high standard and in the U.S. at least they represent extremely good value for money.
But yes, I'd still walk past one to get a Clifton.
