Traditionally, 1OA is more valuable or very close to more valuable than 3+5.The fact that this was a near 50/50 poll shows most believe it's a valid question. Unless it's a complete toss up at 1OA, it's certainly a valid question whether you'd prefer 1 or 3+5.
Thats not to say the right answer is 1OA over 3+5. In hindsight, I think we can say that Lafreniere is not multiple tiers above everyone else. However, the draft is not operated in hindsight. There wasn't much debate in the months leading up to the draft over who'd go 1OA. Lafreniere was regarded as the best without much debate.
The early sample doesn't tell us much. Stuetzle has 13 shots in 9 games, Lafreniere has 18 in 10 games. They are playing about the same amount per game (Lafreniere is playing 11 more seconds per game). The difference statistically is that Stuetzle is shooting 30.8% and Lafreniere is shooting 5.4%. Thats what you get with early season small samples. They'll both shoot around 10-13% at the end of the season. Stuetzle's going to start missing on a very high percentage a lot of his shots, and Lafreniere's going to start scoring on more than a normal number of his shots. Thats how shooting percentages work in hockey. Looking into their advanced stats, Stuetzle has a 47% CF%, and a 29.61% xGF%, while Lafreniere has a 48.39% CF% and a 48.14% XGF%.
This idea that Stuetzle's somehow outplaying Lafreniere is what's silly. Stuetzle has gotten luckier so far. Lafreniere's gotten really unlucky (3.28 on ice SH%). Both guys so far look like NHL'ers right now, albeit not impact players yet. They are somewhere in the vicinity right now of last season's three D+1 rookies.
