Both openers come back completely gray at almost the same rate, so the difference between them lies in how much their hits actually tell you.
Planning the second guess

All five letters miss 9.7% of the time, leaving 228 words in play. Of the 728 follow-ups checked here, IRONY leaves the fewest possible answers on average (6.9).
After SLATE
All five letters miss 9.7% of the time, leaving 228 words in play. Of the 728 follow-ups checked here, IRONY leaves the fewest possible answers on average (6.9).
How these two openers fit together
LEAST and SLATE share 5 of their 5 letters (A, E, L, S, T), so as a pair they only cover 5 distinct letters. Treat them as alternatives rather than partners, because playing both wastes most of the second guess.
Played back to back, LEAST then SLATE earns 6.48 bits of information in total, 0.63 bits more than the better word manages alone.
