In my (very limited) tests, compression was only slightly worse > than lzma, and performance was much better. On my typical data it is much worse than LZMA. Actually I do not see a reason to use it because of worse compression ratios. I am talking about libtiff usage here, of course bzip2 utility is widely adopted as a general purpose compressor and LZMA stuff is not on par here. If we want to bring some new codec in libtiff world we need something that has clear advantage over the existing ones, either compression ratio or something other (decomression speed, like Bob mentioned).
