What batteries are regarded as the ultimate for solar systems?

When I bought my system last year (described in a thread elsewhere on this site) I did a lot of investigation on batteries and ended up with two Concorde SunXtender 305Ah (100 hour rating) batteries. These batteries could cope with the large temperature variations in the Norwegian mountains where my cabin is (-30C/-22F in the winter to +30C/86F in the summer). They also cost about twice as much as "branded" AGM batteries sold by many of the big stores in my country.
My question is: Are the Concorde batteries considered as the "state of the art" in maintenance free batteries?
Thanks!

Re: What batteries are regarded as the ultimate for solar systems?
i think i would consider them one of the best and there are better ones out there too as is evidenced by cell towers and such. i am prejudiced as i have 1 too, but odds are there won't be a marked difference between say mk/deka and the concordes. -
Re: What batteries are regarded as the ultimate for solar systems?
In no particular order, the following AGM battery brands and manufacturers seem to enjoy very good reputations here in the U.S.:
Deka and MK (manufactured by East Penn)
GNB Absolyte (manufactured by Exide)
YUASA (small batteries)
Sun Xtender and Lifeline (manufactured by Concorde)
Trojan

Is the Deka/MK Battery 8AGC2-DEKA the equivalent to the Concorde
Pvx-2240 6V, 224Ah (24Hr) Sealed Agm Battery.

Pretty open question,
Do you consider total life cycle cost? in which case cheaper batteries might win.
Do you chose estimated failure rate? Cost per AH? Or?
