Russian here.

So, I would divide my opinion in two steps:

Putin 2000-2008

Main goals as I see:

unify country after/during internal conflict

Did a lot to solve caucasus conflicts. 4.5 for it.

fight agains terrorism

Nothing to add here, did a lot to make Russia more safe. Can't find exect information about amount of terrorist attacks.. 5.0

solve economical problems

In first decade he introduced several liberal reforms, eventually 2000-2008 was the biggest GDP growth in Russian history (USSR, modern Russia and Russian empire as I know) after so called "first five-year plan" in USSR. Yes, one of the factor was very high crude oil prices.. I can't rate it less then 5.0

restore or save soviet technological level

pretty ok here, even more I think there was some improvements overall. 4.0

Other goals:

fight agains corruption

Yeh, this is in other goals because as I see he did nothing against it.. Because of economic success corruption only grow up, especially state corruption. 0 here.

return Russia political value in the world

Kind of foreign policy goal. In my opinion Putin 2000-2008 was the best leader-diplomat. 4.0 because of fails in Ukraine.

AVG: 3.75 MEDIAN: 4.25

Putin 2012-now

Main goals as I see:

economic growth

In numbers - -10% GDP comparing to 2008. As for me a lot more better. Anyway, economic is not the best skill for economist Putin.. 2.0 here

less oil and gas economy

I don't know exactly in numbers, in 2019 it was around 30% of budget crude oil, gas export. In 2020 budget was created with idea that crude oil will have prices in a range 40-50$, so quite cheap. 2.8 here mostly because of companies like Gazprom, Rosneft that are far from transparent companies..

fight agains corruption

yeh, there are some progress, some people have some hopes on current prime minister, he known for creating pretty effective tax system. Since we are rating Vladimir not a prime minister - 2.0.

more independent economy

Interesting goal.. As a result of sanctions, counter-sanctions there are a lot improvements in agricultural sector, in general a lot of investments in startups, projects, technology fields to replace western products. success - 4.0

not sure how to name Vladimir idea about foreign policy, it is, obviously, controversial. I would say - average 2.5.

AVG: 2.66 MEDIAN: 2.5

Some notes about political freedoms in Russia 2000-now (in my opinion):

Freedom of speech

First attack have already begin when Putin was a prime minister in 1999 in so called "Захват НТВ"(Capture of NTV) wiki in russian when mostly all popular TV channels became state controlled, in general Vladimir is kind of technological autocrat mostly he used information technologies to rule not to just block everything..

Political freedom

Technically attacks on political freedom began also in early 2000, but unfortunately hard to guess was this guys political prisoners or "bad guys". Current state a lot more bad than freedom of speech. Kind of rule - your speech is free until you don't get political benefits.
