I’ve read that the Meteor 700 is a built up Meteor Minor 500 whilst the Super Meteor was built up from two Bullet 350 engines. True? Why make two concurrent designs in essentially the same displacement but with different engines? Which was the better, less stressed and more reliable machine?

Here’s a Meteor 700 for sale. The ad says pre-unit, perhaps that’s the difference with the Super Meteor?

The term preunit doesn't really apply to RE twins, IMO. The twins were never "unit" designs, like the 250 single was.
RE twins had separate transmissions right up to end of production of the Series II in 1970.

As far as the difference between Meteor and Super Meteor, I believe it was mainly redesigning components like cam profiles, and raising compression to gain a few extra HP.
From what I've read, in the early to mid 50's, the UK suffered from poor quality petrol , so the machines of that era had to keep compression low.
But as better quality fuel became available, motor specs could be increased, thus providing better performance.
I'm sure it's a bit more complicated than that, but the above is probably a fairly accurate statement.
I own some early to late 50's twins and the crankcases are virtually indistinguishable from each other, so I can't comment on the ancestry of the case designs.

In regards to what is more reliable etc.etc. the less stressed design will logically be more long lived and reliable.
So, a low compression 700 or even 500 would be more desirable from a maintenance standpoint.
Since your focus is on the 700 twins, lets' go beyond the Super Meteor and see what happens when a design is pushed to it's limits...
Read about the last hurrah of the 700's, the beautiful but fragile Constellation @approx.50-52 HP : case fretting/flexing caused copious oil leaks (which helped establish the moniker- Royal Oilfield)
And outright blowups were all too common when these machines were pushed to their limits for extended periods of time.
Today, they are few and far between for obvious reasons; and were the impetus for RE to redesign the motor to allow for an increase to a full 750 (736cc actual)

Then, what is a "Meteor MINOR?"

In Gordon May's book/bible of Enfield models it seems that the Meteor Minor first appeared for the 1958 model year,
with the new engine dimensions of 70 x 64.3 for a 496cc twin. (ie a short stroke engine)(and genuinely a short stroke).
And a 2-1 exhaust system.
The Tomahawk was also updated from 1958 based on the new Meteor Minor.

Compared to the previous 500 Twin of 1957 and earlier, 64 x 77mm also 496cc.
Also sold as the Tomahawk, with some changes

I have had four Interceptors, two Series 1s and two series 2s. My 59 Conny with it’s single 10tt9 carb gave a seat-of-the-pants feeling of more torque and more power than any of my Interceptors. Fragile though it be I’m sorry I sold it to buy a S2 Inter!
My Series one with the hot cams comes as close to the Conny in performance, but no camshaft “quieting ramps” means it’s noisy like it too. Btw I think the Indian Chief had the hot Conny motor. No?
Give the early Meteor’s credit for smooth performance though.

Looking at the illustrations above the difference between the Meteor 700 and Super Meteor seems to be the frame. The latter appears to have a newer frame design, while the former appears to be a Bullet type frame.

The Meteor ran from 1952 -55,SM 55 onwards.Meteor had nothing to do with the Meteor Minor which came later on.Meteor began the two 350cc
singles theme,kind of strange as oil delivery volume was the same as one 350cc single.
Meteor ran dynamo-distributor,a few different timing chain tensioner versions came out with the Meteor then were changed back to the original tensioner.SM alternator,SM different cyl and heads more cooling fin area to deal with increased compression and power,
Larger bearings on the big ends
Some describe the SM the best Enfield ever,most dependable and easiest temperament.

If Royal Enfield India comes out with a Super Meteor based on the new Interceptor engine I'd buy it. I'm a big fan of the look of the SM's nacelle/casquette instruments over the Interceptor's two separate gauges stuck to the handlebars.

Shouldn't be to hard for Enfield to do,they already have the nacelle from their singles,it maybe on the production line already as RE are not real slow at adding new models.

Also the 55 Meteor had, for a year, a new frame and mn2 magdyno electrics.
