For 8 bits I use Tiff or 100% JPEG (depending on alpha) but be wary of using TIFFS with LZW for 16 bit.  AFAIK After Effects is the only application that allows LZW compression for 16 bit TIFFs, as it’s not a great algorithm for 16bit images and the compressed files are often larger than the originals.  So you have a case where it takes longer to render/read because of the compression/decompression process and the files can be larger than they were in the first place.  Photoshop and other apps disable LZW compression for 16bit TIFFS, but AE allows it.  YMMV.

DPX is fast in AE but lack of compression and no 16-bit or float support is deal killer. TIFF LZW or EXR (half float) are superior depending on needs.

what is your go-to intermediate image sequence for Ae? i.e render heavy renders in Ae to save time later in the final render to container/mp4.
 
I moved to DPX a few years ago (after years of futile use of PNG sequence). but now I am thinking to shift to EXR half float in Ae. the size of DWAB/DWAA/ZIP is very small and I see I get the same quality (I do have to remember to use preserve RGB in interpret footage). the render speed is almost the same. the read speed back in Ae is faster for DPX but only slightly.
