T mobile internet in Louisville? Yay or nay?

Experience locally with T Mobile internet. Wee worried about the actual site repeatedly mentioning high traffic times might slow down service.

That said, AT and T is a never ever again ( though happy union ).

Will probably stay with Spectrum though every minute of the day my monthly bill seems to covertly go up.

Looked into Iglou to support local but my word - from non tech eyes - looks so terribly slow?

Thanks for any lived experience.
