A lot depends on the nature of the White regime. I think in most cases, it's going to be fairly "normal", and widely accepted by the wider world. This alone is a great boon, compared to OTL. It means access to foreign investment. As has been mentioned, the lack of needless genocides and purges is a massive advantage. The retention of the educated/moneyed class is also a sure bet in the case of a fairly moderate White regime, so that's a plus as well. In fact, many Russian exiles will return.
It must also be understood that the myth of Soviet progress is just that: a myth. It's bullshit. Their industrialisation was highly inefficient, ludicrously selective towards what Stalin and his thugs figured they'd need, and not-at-all ideal for long-term benefits of growth. It was also almost entirely done via commie-typical "redistribution", which means they just looted money and materials and energy elsewhere, and dedicated to the programmes the regime wanted to prioritise. They essentially emptied their right pocked to fill the left pocket. Gain in absolute terms: minimal. (And ultimately even zero, because of efficiency losses involved.)
Almost any other regime would have done better than the USSR, which was ultimately a total failure in every conceivable way. It became a dirt-poor shithole with a tiny economy and a beaten-down dwindling populace, and all available means were pillaged to put into the over-sized army (which was in itself a bureaucratic nightmare, and far from an efficient machine). The USSR was a disaster, which inevitably collapsed in on itself.
Even a totally insane White regime, with the worst loons in charge, would probably not be as inefficient as the USSR. After all, Nazi Germany (which was just such a regime) was economically retarded, too, but not as moronic as the USSR. Rle of thumb: the closer you get to a full command economy, the worse it is.
and yet dispite all of that we as a species have learned fucking nothing and we still have people who want to try this shit....again.
