Blue
Ravenous Bugblatter Beast of Traal
Two reminders.
1. The shape of the distribution is different. So adding a static number is a poor fit to simulate it. And it can raise the cap.
2. 5e rewards specialization. The difference between the average of 4d6K3 and 3d6 is irrelevant for this discussion. The primary point of interest is between the highest of six of each, then comparisons of the second highest of six from there, and then some minor quibbles, like how many penalty modifiers. Looking at it from the average roll will not mimic each other at all in practical terms within 5e.
