The smaller (50A) the alternator, the easier to rotate its axle??

All alternators are fairly inefficient. However, lightly loaded alternators are more inefficient than heavily loaded alternators.
The idea behind using a smaller alternator is that a smaller alternator will be driven closer to its maximum rated output power.
If it's possible, you might try to get an ammeter and measure your car's loading. However, with a older diesel, the only significant loads I can think of would be your exterior lighting.
