I do care about DR but i want more DR at high iso where canon is better !
At low iso i get by most of the times
The issue is mostly usable DR, in that the DR is there at lower ISOs, but the lower stops of detail (darkest pixels) have their signal drowned out by read-out noise (such that they're effectively unusable).
IRC The Canon sensors are fairly flat with DR as ISO increases (because the loss in DR as ISO increases is masked by the read-out noise) and only at higher ISOs does it start to drop as expected. Whilst, yes, there is a bit more at higher ISOs than a Sony sensor, the DR on the Sony sensor continues to increase as the ISO lowers (as it's not drowned by the read-out noise). I'd happily trade a tiny (and probably not visible) high ISO DR advantage for a large low ISO DR increase.

Please Canon, I need 5 more stops of DR to squeeze in level 254 and 255 of my JPEGs. That would make a world of difference.
You could initiate one of those RAW vs JPG flame wars right there . But, yes, if you're shooting JPG then I'd suspect large DR isn't that relevant, as it's more about manipulating 12, 14 (or higher) bits of data in a RAW file.
One thing to note here is that, even with a Sony sensor, the amount of tonal detail in lower stops will still be less than in the higher stops (basically twice as many levels in each next brighter stop). Thus exposing to the right will still result in better images on a Sony sensor - it's just that when you can't, you at least get something (more) usable in the lower stops than current Canon offerings.
