Verdict

The call

The clearest difference is in-app purchases: PhysicsLab at none against Photronium's 1. PhysicsLab also leads on iOS requirement (13.0 vs 16.4). Photronium's advantage is ads (none vs shown) and update cadence (monthly vs every 3 months). On price, review sentiment, monetization model and device support there is nothing between them.
