Better format to save

[huguito]

I save files that have lots of layers, some panoramic or composites that tend to be large and fat.
What's a better format to save them if you want to have the most flexibility of coming back some other day and re-edit or change settings on existing edits?
Tiff?   PSD?
Do you have a preference?
Why?
What specificaly makes one better or different than the other one?

Thanks

Personally, I use TIFF ZIPped

No reason to save PSD, TIFF provides everything you'd need (other than Duotone support). TIFF is an open format, PSD isn't. For long term archival storage of images, stick with TIFF.

https://helpx.adobe.com/lightroom/help/supported-file-formats.html  is the Lightroom 5 help page on supported file formats.  Here is part of what is says about tiff.

"The TIFF format provides greater compression and industry compatibility than Photoshop format (PSD), and is the recommended format for exchanging files between Lightroom and Photoshop. In Lightroom, you can export TIFF image files with a bit depth of 8 bits or 16 bits per channel. "

Lightroom will not open a 32 bit psd file.  It only supports tiff files in 32 bit. 

So, it seems that Adobe itself prefers tiff over psd. 

I use tiff.
