Which factory assembly manual to get?

[67L48]

For the 1967 Factory Assembly Manual, I have seen four different ones available online:

• There's the bound one with the red art on the front
• There's a loose-leaf one with blue art on the front
• There's a another blue print loose-leaf version
• There's a loose-leaf with green art on the front

I like the idea of a 3-hole punch version, so that I can lay the manual open flat.  However, those who sell the bound (red artwork) manual generally make claims about it being higher quality than the loose leaf versions.  For instance, Rick's discription states:  "These are quality perfect bound books, not hard to read loose leaf like some others."

So, is there really a difference?  Should I trade the convenience of a loose leaf manual for the quality of the bound one?

Thanks.

Here's yet another loose-leaf version:

I have the repro bound one for a '68 from Rick's (the top one you show.) It's well-done and easy to read, and lists all the part #s, places to put sealer, torque specs..all of it. It's comprehensive and
very detailed. Expensive, sure, but well worth the money.  I can't speak for the loose-leaf versions but anyone doing a 1st-time frame-off needs the bound one. My 2 cents.
