The cab steps do look like turds. But the ride height? BLI has obvious quality control issues and with the decoder and wiring stuffed in there, the shells have a tendency to sit too high and need to be properly seated. In a flat on side view, the BLI also has more air above its trucks. Other details are also different between the Kato and BLI. See below, Kato on the left, BLI on the right.
