I can only speak from my experience - I've found Verizon's 3G mobile broadband (non-mobile - at home!) is much faster than Hughesnet.
Had hughesnet for 2 years, never more than 1.0Mbps download; occasional outages with weather. Moved to Verizon 3G using a Novatel MiFi 2200 modem connection. Usually 1.5-2.0 Mbps download; but more importantly, using it, it is noticably more responsive & faster page loads. Also have been thru a couple of storms that would've dropped the Satellite. I would NEVER go back to satellite.
The 5Gb download limit is a concern. However, my Hughesnet was 300Mb per day FAP, and we triggered it a few times over the 2 years; however, when I examined my monthly usage, it seldom went over 3Gb - the big download days were balanced by weekends away from home, days of little use, etc. I find the same now - I'm running usual months around 2-3Gb per month, although I have days where I'm over 250Mb - the average over the month is a big help.
