Legacy satellite talks to satellites over 35,000km from the surface of the Earth up in geostationary orbit. Each provider has a small number of satellites and the speed of light delay alone results in pings over 500ms. Also the providers are pretty shady, and data transfer caps have to be really low because there aren’t a lot of beams to serve all the customers. Legacy satellite is terrible and I wouldn’t wish it on my worst enemy.
Starlink has 1000+ satellites at ~500km, the latency is way lower. There is currently no data caps. There is no contract for a fixed duration. It’s a totally different beast.
I’d check out the Starlink subreddit to get real users experience. You may wait a while to get setup, there is huge demand. From what I have read on the subreddit recently, depending on location there may be short outages of a few seconds every hour and some longer “beta update” periods of 10s of minutes a couple times a day.
If there is a TMobile 4G tower nearby TMobile now has a $50/month unlimited data transfer Home Internet service that uses their 4G and 5G towers. It might be good to weigh this against Starlink. There are videos reviews of this service from 4 or 5 people on YouTube. TMobile tracks how many people near each tower they have sold this service to to avoid overloading the towers. 8 years ago when I was stuck with legacy satellite with a 425MB/day (yes!!!) data cap, it was Verizon building a 4G tower near me that saved me. Back then I had to create my own homemade setup with a portable hotspot but the TMobile solution is way nicer.
