I haven’t found any interesting modern-day philosophers. They might have some good arguments here and there but nothing in impact compared to some of the medieval or classical philosophers. The problems they are dealing with — e.g. science, language, society — are also very resistant to simple resolution. Then again, most of them are operating within the paradigm of materialism, and the dominating majority are influenced by left-wing political ideologies, which have become the war cry for equality, rather than explaining how differentiation emerges and becomes real.
