Verdict

The call

The clearest difference is price: Piano Sim at Free against Jublag's $3.99. Piano Sim also leads on update cadence (every 2 months vs every 20 months) and iOS requirement (12.0 vs 18.0). Jublag's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
