Starlink and Swarm don't meaningfully compete. Starlink is a V-band (GHz-territory) system suitable for high bandwidth applications, but requiring good line of sight, lots of power, and a big, complicated phased-array antenna (or I guess you could maybe have something actively steered instead, but SpaceX doesn't seem to be pursuing that).

Swarm is a VHF system (hundreds of MHz) that can't come anywhere near Starlink in terms of bandwidth, but can operate with much lower power and a small, simple, dirt-cheap antenna. The tradeoff is that you'll end up paying way more per byte. But for their intended applications (basically, embedded IoT-type sensors), you don't want to transmit/receive much anyway, and keeping BoM cost down is key.

In other words: there's basically no application where someone might be choosing equally between these two options.
