Looking at their website, it seems connectmenow uses conventional geostationary satellites, which suffer greatly from latency (can easily be upwards 2 seconds). Starlink is low earth orbit, which enables them to give you latencies below 100ms.
On top of that, you need a bulky parabolic antenna that you need to point at the sattellites accurately, which can be a pain for installation and delivery. On the other hand, starlink has an antenna you just plug in and point straight up, and it works.
I also happen to hate muskrat, but I have to admit starlink is the superior offering.
