The difference in when the error is flagged is a large difference, though. Usually, runtime semantic errors won’t be flagged until the program tries to actually perform some nonconforming action. That lets the programmer work on unrelated issues by simply not exercising the defective path. Compile-time errors, on the other hand, ensure that the entire program meets some baseline of correctness before any of it is run. Neither is necessarily better or worse than the other, but they are categorically different things that have their own effects on the experience of writing programs.
