The team came from the IPFS and Scuttlebutt worlds. "Better" is relative to your design goals. Iroh is better for point-to-point connections & localfirst. Matrix is better for chat rooms. Etc. The general logic of atproto was to serve large scale publishing with an open model that doesn't seriously degrade the UX. The scale orientation means - at least until the non-public spaces land - you're syncing a lot of records to provide an alternative microblogger to bluesky. The account hosting system, however - the pds - remains exceedingly cheap and easy to run. Pros and cons, matching with the design goals.
