Different cell vendors will potentially be very different with respect to level of service so Verizon could suck and T-Mobile could be great or they could both suck. The best way to know would be to have someone on those services check someplace like Speedtest at various times and days from your place or to try the service being prepared to cancel if it’s not good.

But yes if you can get decent fiber optic service then that would likely be better. Although there are folks in my rural area that are always complaining about some ISP (frontier, spectrum, ?, can’t remember).
I’ve only ever heard good about Starlink.
