11/70 - original or 570 model more desirable?

At first i treated this as troll bait.  Then thought about it some.

First despite caveats I don't have space so the likelihood is nil.
Also its outside what I do collect, that crates conflicts for space,
power and documents.

The reasons I could give for one or another are multidimensional.

Esthetic, the early 11/70 was of an era and that had a look.  The later
one as well.

Historical significance,  thats limited to the general model the biggest
fastest 11
made but having say serial number 001 or whatever was first off the line
for sale is
as significant as the last one off the line or both.  Also any along the
way that had
a instruction set or major hardware difference of some historical note. 
An example
of that would be an 11/74 as those were truly rare (maybe 4 assembled).

Operational, as in running it. definitely a late model near last built
as it would
have all the ECOs, be the least old, and should run well

Opportunity to save a machine that might be scrapped.  In itself thats
important
and it would be model independent.

Being a Qbus 11 collector there are still critters I might gather.
