FWIW, the M1 uses less fuel (which doesn't have to be 'jet fuel') than the T-80.
That said, which model M1 matters. All have good crew protection, shoot the same sabot rounds - but the electronics package differs. I've seen reports of the most modern Leopard IIs Ukraine has recieved being particularly effective at night. Older ones, not so much - and the M1s being sent are on par with those older ones.
