These points are limited to the essentials - there will not be enough time to write about all the successes he had! Especially as the Failures are probably more worthy of note, in my opinion.

Who had the Biggest
Economic Impact?
Stolypin arguably had more successes than Witte but still
failed to address key issues such as living conditions and
production increases. It can also be argued some of his
successes were down to the pressure put on by the Dumas
Witte made good progress in terms of production, but
through means of more hardship on the peasants. The
Trans-Siberian Railway was an improvement for transport,
but still proved not good enough during wartime Russia.
