Best long term path for Russia

What would you consider the best path for Russia, primarily in terms of stability? I’m not focusing on military or industrial power. I've played Savinkov's 'Codification of the Regime' path, as well as Solonevich's monarchist and republican paths, but I find only Savinkov's vision viable in the long term (though I've played only a fraction of reworked Russia); the others aren't (i'm talking about conservative and reactionary ways).

Do you think socialist regimes would survive and reform over time, or would they collapse like the USSR did in real life?
