ST best T-Mobile mvno?

I've been using ST with their ATT sim for years and it's treated me great, however I recently moved to an area where I get no data, with further research it turns out ATT has no coverage where I now live and it seems to be predominantly T-Mobile. I've been shopping around and it looks like ST is still the best mvno $45 for 5gigs, does anyone else have any suggestions before I buy the ST tmobile sim from stbyop?
