Oh, the EEA route is significantly simpler. To give you a sense of perspective, I am a non-EEA migrant to the UK. To settle in the UK, there was a required minimum salary requirement that I had to meet (which has gone up significantly since my arrival. It is now £35,000.) and if I did not meet it, well, there is the door. By contrast, an EEA migrant need earn nothing in the UK (the self-sufficient route) provided s/he is not a burden on the state.
My entire immigration process, as a single person, cost about £6000 and that is not including citizenship and getting a British passport, which was £1000 more. By contrast, some EEA citizens (not you of course) have whinged on these forums about paying £65 for getting a Permanent Residence Card.
As a person settled in the UK under UK laws, I must earn more than £18,600 to bring my non-EEA wife into the UK. While I earn more than that, 43% of the British population does not meet this requirement. Hence this requirement is being challenged in the Supreme Court.
There is practically no chance of bringing in your parents (only 34 visas issued in the past four years) or adult children born outside the UK. By contrast, an EEA citizen has the undeniable right to not only bring in their non-EEA spouse, children & dependent parents, any member of their or their spouse's family who has, at any point of time in the past, been dependent on either themselves or their non-EEA spouse, must be treated more favourably than a non-EEA citizen applying under the UK Immigration Rules. The ECJ has interpreted this to mean that this can include half-brothers and nephews who had once shared a house with the EEA citizen's non-EEA spouse at any point in the past (Rahman Judgment).
Some more observations here.
I did say, don't get me started.
I do not mean to denigrate from the issues you are facing with regards to your personal immigration history. The EU laws are binary in nature; either you tick all the boxes required 100% and get it all or you miss out on a single box and fail. There is no half-way house. By contrast, the UK Immigration Rules do allow some level of discretion because they look at the whole picture of the person's circumstances. Of course, such discretion can be used either for or against you.
