Stalin's point was that it was better to focus on solidifying socialism in Russia over launching a suicidal attack on the peasantry immediately after establishing state power Stalin was wary of the peasantry, but did not follow through with Trotsky's plan.

Further, there's no evidence that the USSR would have been better off administratively had they elected Trotsky. The Fourth International itself was a mess, and Trotskyist parties are notorious for their lack of discipline and their tendency to endlessly split, rather than form a unified line and push for it. The Trotskyist parties that survive actually often return to Marxism-Leninism because of this, because Marxism-Leninism is correct.
