Fortec is a good company. I and others have sent them email requesting certain features and they have listened to us.
So they listen to their customers. They also reply to email sent to them.
They also come out with software updates for their receivers.
I have a Mercury II and it works. Pretty much bug free.
Fortec also has a customer survey on their web site. They want to know how you feel about their products.
Then they have videos on their web site to help you with your installation...

And this used to be the way all companies were (in general, not just satellite). i.e. Listen to your customers, keep your customers happy, give your customers features they want, etc. These days this seems rare!
FYI - I am not familiar with the other product you mentioned.
