A handful of Poul Anderson's stories were revised for later editions but the vast bulk of his enormous canon we read as it was originally published whereas HG Wells' The Time Machine was endlessly revised and rewritten both before and after publication which is why it became what JB Priestly called "...that little masterpiece." (Barely discernible in the image.) Wells should have written less and better whereas Anderson had the capacity to write much and good.
Like Anderson, Wells combines speculation with action-adventure. The Morlocks are the ultimate lurkers in the dark. And what a contrast between the Time Traveller's civilized dinner parties at Richmond and the Eloi's informal frugivorous meals in 802,701 - this highlights the adaptability and plasticity of humanity.
