I have had Aerodata for 10+ years and just use it for logging. It is very up to date and comprehensive. Only drawback is that it has not be developed for years so doesn’t have anything more than basic search routines. It is very much construction number driven, for instance you can not produce a historic register, or historic airline fleet list from it.  I would be tempted to switch to something that was more searchable but as up to date.
