Superman VS Sentinels

Ok so i'm going to pitch a hypothetical scenario and hear what you guys think.

If Lex Luthor created the Sentinels and they had a kryptonite heart like Metallo, would Superman be able to beat them? (the Sentinels has hearts the size of 3 square meters.

Depends on how strong sentinels are and their weaponry and tools. If they can fly fast enough to keep close to supes or have decent strength to inflict damage on him then yes. Also how many sentinels is a huge factor. How the battle takes place also matters alot i.e. whether the sentinels get the jump on supes or if supes is aware of their approach etc.

Superman has a very good track record against Kryptonite laden robots.
