Rather than just attempt to generalise things from what I know, I decided it would be better to go to someone I know is a direct expert for direct quote. A friend of mine from the Polish Army, who has been inside both Leopard and Abrams tanks on familiarisation, and works as a reporter for military technology. I've never met anybody as deeply embedded into tank technology as him.
He's offered some notes on the modern Abrams FCS, but will bring some more later on why it sets it apart, that I can carry across into here once he's back from his shift. I think he slightly misinterpreted my question at first, but hopefully some of this information is interesting for the moment until I can get the more full answer later.
New FCS/Sights for M1A1SA, M1A1FEP, M1A2SEPv1, M1A2SEPv2, have such functions.
1. Day sight have 3x and 10x zoom.
2. Thermal sight have 3x, 6x, 13x, 25x and 50x zoom. Same for M1A2SEPv1/v2 commander CITV. M1A1SA/M1A1FEP SCWS cupola have day and thermal sights comparable to panoramic sights of european tanks.
3. Due to new laser range finder and FCS software, FCS allows to fire all main gun conventional rounds up to 5000m, LRF can lase distance to targets much further, around 10000m.
4. Thanks to new LRF, a far target location system was integrated in to vehicle FCS and BMS. It means that by using LRF range + azimuth data + own vehicle position thanks to GPS, FTL system can calculate precise coordinations of targets, these can be then distributed by BMS to other friendly units, higher echelon command, or used for artillery or air strikes.
FTL capability will be further enhanced in M1A2SEPv4.
Because commander CITV will be upgraded in to CIV, with new thermal sight, new day sight, laser range finder and laser pointer
Thus tank commander will be also able to use laser pointer for guided missiles, bombs and munitions.
Later when i return from work i can write more
EDIT- He also dropped this just before he left there
Leopard 2 FCS did not changed much from time it was inducted in to service. It is US design by Hughes. However its old design, gunner still uses old WBG-X thermal sight which is 1970 tech.
Modern M1's uses now 2nd generation FLIR which is XXI century tech
Also Leopard 2 sight is kinda meh. Day sight have only fixed 12x zoom narrow field of view. Thermal sight have 3x and 12x zoom compared with 50x on the Abrams. On Leopard 2A5 and newer commander optics improved tough with new PERI. AFAIK Swedish, Spanish and perhaps Greek Leopard 2A5/A6 variants have redesigned day sight for gunner with 3x and 12x zoom. Thermal sights stay the same old, obsolete WBG-X.
Again, more when I get home. Got my detailed docs there.
In effect, as he surmised quickly, the Abrams' FCS involves more connected systems that reduce time to engage, higher resolution sights, VASTLY higher magnification, and more tools available, while the Leopard 2's have some individually interesting systems like the new daysight, but altogether are a bit of a mishmash that aren't as cohesively upgraded and integrated together on any single variant in service.
What he's heard was that while any tank can be that accurate, SE is judged on time to engage as well, which the Abrams is monstrously effective at. ROF isn't constrained by the loader/autoloader any more, but by the crew interface.
