We operate both networks and have come to a basic conclusion that Hughes HX is the way to go from an end-user point of view. From an operator point of view more or less it's the same unless you're looking at VNO options where Hughes HX takes the lead.
An excellent power-point presentation can be downloaded off our website from, http://www.wafa.ae/
Ease of installation - Hughes takes the lead on this one. It's literally a plug and play system. This is what makes Hughes the darling product of the troops deployed in Afghanistan and Iraq.
Ease of maintenance - Again Hughes takes the lead here. iDirects have the issue with option files . E.g. if an upgrade from te hub end is done and sites are powered off for any reason and misses the upgrade. Then the option file ( configuration file ) must be manually uploaded into the modem. With Hughes it's like a multicast and even if the remote modems are powered off the moment they are powered back on they get the update and site remains up and working.
Costs - Yet again Hughes leads the pack with very low terminal costs versus iDirects.
End of the day, it's also question of cost vs use. If you need VPN 8hrs a day, find a 128 or 256k dedicated pan with QOS. This would provide almost the same as dialup. Idirect would be an ideal choice here.
If you need a few hrs of VPN, and more hrs of std. internet, go the Hughes way.
