What is the difference in writing style between john keats's Ode to a Nightingale and Shelley's Ode to a Lark?

There is no difference in writing style between these two well-known poems, and they are both representative works of English romantic poetry in the19th century. It is easy to find the characteristics of poetry in this era, please refer to it.

But for the appreciation of these two works, I would like to give you some suggestions: poetry is the literary form with the strongest emotion of the author. To appreciate a poem, we should not only read the feelings from the color of the text, but also feel the author's feelings through his growth experience, life experience and ideal ambition. Shelley and Keats are only three years apart. One comes from a noble family and pursues freedom, while the other comes from a poor family and struggles to survive. At the same time, he created two literati with different temperament, and the difference of their works is reflected here.
