Best Internet Providers in St George?

I am going to be moving to St George and working from home full time so I will need a good reliable internet. I used to hear that TDS was the best but now hear its awful, is that true? Also where I am moving to does not have fiber access. I feel like any company that isn't TDS only has speeds up to like 30 or 100 mbps where I would probably need at least around 300. Any help would be great!
