besides the size difference, is there any way to tell by markings or writing on them?

depends on the ecus:
P08 P70 P71 P91 P54 were specific ECU for DOHC SOHC motors such as D15B, B18B, ZC, D16A

others which came in JDM version always have a number at the end such as:
37820-P30-001 vs a USDM 37820-P30-A01 (A meaning America/US, C= Canada, J=Japan) but usually JDM ECUs use numbers such as XXXXX-P30-000 or 001 or 901 or N51 or 002 or 902
