It's like as if these clowns had fantasy goggles on about how cool and awesome the Abrams was. But remember what I said about their Honeywell engines...
The Abrams is a good tank. But like all tanks it was designed during an era when technology was very different. As tanks go: it is far better than Russia's T-90.
A problem with the Abrams is that it was designed for Western Germany during the 80's which had far better road systems than Eastern Europe, and different weather conditions. The Abrams is a very heavy tank, it also requires a sophisticated level for maintenance, and it is designed to be used in a different way than how Russia uses its tanks. Ukraine is coming from the way Russia fights wars.
It's a good tank, though you can only drive around downtown Frankfurt in it, because it breaks down elsewhere, but it's a good tank, very capable. Well, provided you have a very specialized maintenance crew with it when you are driving around in German towns. (No drones please.)
I can't speak towards whether the T90 is any good at whatever but this really feels like the Tiger tank argument all over where on a stat card it beats the shit out of any other tank except of course in the real world where it boiled to our wondrous wunderwaffe tank vs. 15 T-32s
