Since double and float represent the same data type (usually), which is preferable?

It looks like on ATMega based boards, float and double are equivalent 32-bit (4-byte) data types.

However, on the Arduino Due, doubles are 64-bit (8-byte) where floats are 32-bit (4-byte), same as the ATMega boards.

I also saw one source on avr-gcc that listed double as non-standard.

So, when writing code for ATMega based boards are floats preferable to using doubles, since that would make the code equivalent for Due boards? Or are doubles preferable for any reason?
