It is salutary to compare the character and achievement of the first and second 'generations' of English romantic poets and philosophers - of whom the leading spirits were Wordsworth and Coleridge (born 1770/2) and Byron and Shelley (born 1788/92).
In terms of achievement we could say that W&C were each first rate of their kind - Wordsworth ranked behind only Shakespeare and Milton as a poet; and Coleridge being the leading all-round intellectual of the early 19th century as well a a poet of the second rank. Byron was extremely famous/ notorious/ influential - but a far lesser poet than W; and Shelley wrote some important essays (and great poems) while never matching the extraordinary depth and range of C.
In terms of virtue - there is no comparison. Wordsworth was a good man, and Coleridge a repentant one. While Byron and Shelley pioneered the inverted morality of the modern global celebrity elite - especially in terms of exploitative promiscuity and self-gratification.
Politically, after the transitional experimentation of adolescence; Wordsworth and Coleridge were conservative Christians; but Byron and Shelley were radical leftists and atheists. (Byron - as licentious aristocrat - being an archetype of the later communist leadership.)
There, in a nutshell - compressed into four persons and a gap of less than two decades - was the decline of Romanticism into modernity; and the point at which the developmental evolution of human consciousness took a wrong turn into incoherence, self-hatred, despair and active self-destruction.
Those who affected to live For the people and poetry were lesser people and poets than those who lived for God. When God had faded even from memory - then so did poetry.
Note: A further comparison might be made between the women: Dorothy, William's sister; and Mary, Shelley's second (de facto polygamous) wife (until the first had been driven to suicide). Dorothy was surely one of the kindest, most generous and most loving of people I have ever encountered in literature; as well as one of the very greatest diarists. Mary was an important pioneer of Gothic fiction (with Frankenstein) but spoilt and selfish; the precociously seductive wild child of notorious radical atheist celebrities.
