Is it same id for iPhone and iPad mini is better or separate id is better?

Always best to use the same Apple ID across all of your Apple products. There are so many benefits such as not having to pay multiple times for things, share passwords between the devices, share photos, music, videos etc

It is generally better to use the same account so that your data is synced across the devices automatically (or close to it). That is unless you plan on using one of them for a business/job scenario. In that case, it might just be better to dedicate one device for your job and another one for your personal use.

The same is better since they sync the services & uses between them. Making a separate one doesn't make much sense & would take more work on your part in terms of maintenance
