That can be a tough question to answer depending on what you're looking for .. you could take the feature comparison approach like you'll find on wikipedia and i think has already been mentioned here:
agreed it's only a small subset, and generally feature comparisons get heavily used in marketing campaigns for some sort of mudslinging or feature bashing. Of course there's always something that doesn't really get addressed when you take a spreadsheet or bullet point approach. Or you could take the microbenchmark approach with something like Richard's filebench project:
IMO the latter is more of a step in the right direction but the problem sets may be very different depending on your applications - it can be a tough decision to determine which numbers matter the most when you have to make tradeoffs .. your best approach is typically to try and decide some form of CTQs for your applications or organizations that take into account the relevant factors (administration, volume management, storage platforms, performance, recovery, operating systems, etc) and match up features and performance considerations concurrently.
I think you'll find that ZFS is an amazing fit for most applications, but in cases where you may think you need directio or non-buffered sorts of behaviour .. you could be at a slight disadvantage. Of course Sun also offer QFS as another high performance alternative .. but like the old mantra we've all heard too many times now .. (everyone together) .. "It all depends on what you're trying to do" ..
