I've only used cross band a couple of times but use APRS all the time. But there is a lot of discussion about the utility of APRS. Certainly seems HSMM-Mesh is much more useful anymore. But hard to beat the tactical application of APRS. I know hams use it when supporting events like big cycling tours to keep track of everyone. It frees up the voice channels from constant needing to let net control know where you are, they just see who's where. It's very handy for that.
