If you do have a choice of ISPs and internet delivery technologies, I recommend, in this order, the following connection types: Fiber, the fastest of the fast; cable, can be good on downstream speeds, but tends to be much slower on upstream; and LEO satellite and 5G internet are both good, but they're still in their teething stages and their performance can be erratic.
Then, there are the connections I can't recommend, but if you have no other choice in the matter, well then you have no other choice. DSL, when you can still get it, is decent with real-world speeds in the double-digit Mbps down and single-digit Mbps up. But AT&T is getting out of the DSL business so you can no longer get it. If your DSL connection goes out, I've had AT&T customers tell me Ma Bell won't fix it.
Traditional satellite internet companies, HughesNet and Viasat are better than nothing if you live out in the country. But their download speeds max out, in my experience, at 30Mbps. Upload speeds are stuck around 3Mbps. The real killer though is the latency. With 300 to 500 milliseconds between pressing a key and seeing a result, video gaming and conferencing are next to impossible to pull off. Both services have data caps that will slow your down speeds to about 3Mbps if you use too much data.
Finally, if you've got nothing else, believe it or not, dial-up modem ISP services still exist. These are cheap but at a top speed of 56 Kilobits per second (Kbps) no one will want to use these today unless they literally have no other choice.
