I also like Xint more, since stacks are more stable - we take the JIT out of the equation. Compile decisions could be different between different runs. If not today, it is not guaranteed never to happen - nobody guarantees exactly how the JIT optimizes and that it is bound to repeat the same decisions on every run.
