When you're dealing with a specific subdomain, it's certainly possible you can exploit known properties of data in that domain to achieve better compression than a general purpose algorithm. That said, it's certainly worthwhile benchmarking (de)compression speed and the compression ratio to see if the difference is actually meaningful enough to be worthwhile.
