Who I have the same questioned this topic

Ok I was with Sprint since 2002 and tried T-Mobile on a prepaid phone and both had download speeds of 70 plus. Sprints upload speed never went over 6mbps but T-Mobile’s rocked! 

I switched to Verizon in hopes that their service would be superior but boy have I been shocked at the lack of speed and consistency. Only thing Verizon is consistent at is being inconsistent! 

Definitely not happy with my switch and should have went with T-Mobile!! 

Have attached my speedtest results
