These SMRs have a 60 year lifespan[1]. The lifespan of a wind turbine is optimistically 25 years for offshore (I don't know whether your stat refers to off/onshore wind.)
Even if the SMR itself were to have a 60 year lifespan, you'll find that the steam turbines attached to it are not really better than the wind turbines. Comparing an SMR with a complete wind turbine is like comparing apples and apple trees.
