Sky TV is outrageously expensive for what it is, but I have to say the Sky Q interface and EPG are very slick, intuitive and user friendly. You can get a close(ish) proximity with enigma, but if I'm honest the UI isn't as good as Sky Q. My wife likes "simple" (my adult offspring don't actually watch a lot of TV), so I have to set things up so it "just works". Luckily we had an enigma receiver before we switched over to sky so my wife didn't take long to get used to it again. The biggest difference where Sky appears more "polished" is around series record. With Q its a one click thing whereas with E2 the autotimers are a little bit more difficult to set up. My wife normally tells me what she wants recorded and I set up the autotimers for her.
The rest of it is pretty similar experience. You can have a nice 7 day EPG and there is plenty of flexibility when it comes to look and feel.
Can't help with that, though I locked myself out of my own account recently when trying to change the email address I have associated with my profile. I didn't receive any verification email to the new address so i had to switch back tom my gmail address to get back on. Maybe there are some issues with site email delivery?
