On what basis did you determine the ratings you gave the batteries?
You have Lifeline as a "better" and a Concord as a "best".

Interesting as how they are the same basic battery

Experience and ratings.

I do not know that a Lifeline is identical to a Concorde but it could very well be.

Edit: looked at a 100AH battery in both product lines. A 100 AH Lifeline weighs 62 lbs. A 100 AH (extrapolated rate) Concorde Sun Xtender weighs 66 lbs. That would kind of show that not all Concorde and Lifeline batteries are identical It's kind of a moot point with me. You can put them in the same category if you wish.

When I was battery shopping back in '04, I inquired about the Concord Sun Xtender versus the Lifeline. I was told by the Concord rep that they manufacture both batteries. They are the same electrically except the Xtender is for fixed applications. The Lifeline was developed for the aircraft industry where the battery would operate in extreme environments. He specifically said do not put an Xtender in an rv.
