So is 203 kg a good bench press?
If that lift is a bench press, 203 kg (447 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

180 kg × 4 — common questions
What is my one-rep max if I lift 180 kg for 4 reps?
About 203 kg (447 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 196 to 210 kg, so the range is the honest answer.
Is 203 kg a good bench press?
If the lift is a bench press, 203 kg (447 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 81 kg × 5, 112 kg × 5, 142 kg × 3, 162 kg × 2, 183 kg × 1, then the working single at 203 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
