TIFF is one of the most open and flexible file formats out there. PNG offers only a tiny subset of what's possible with TIFF. Note that TIFF supports multiple compression formats, lossless and lossy, multiple sample formats and sample counts, very flexible organisation of data layout etc. PNG offers a small number of sample formats, fixed layout and compression, and none of the higher-level TIFF features. PNG is simple and easy to use. But "better" is subjective and by most objective measures it's inferior to TIFF.
