I think that for a beginner, Ancestry is a better starting point. The presentation of results is simpler and I think this helps in the early stages. Take plenty of time to analyse the results. Concentrate on your first page of results and work through these before moving down the list. making sure you understand what you are being told including the limits of the data. They usually offer discounts around high days and holidays (mothering Sunday, Christmas, etc.) so keep an eye out. You will save £20 but the P&P is a sting in the tail just the same.
Then, despite the caveats outlined earlier, you can transfer your Ancestry results to both Gedmatch.com and ftdna.com when it suits you and at no further cost.
I would do these one at a time and after each one, giving yourself lots of time to absorb all this extra data with which you are suddenly confronted.
Occasionally, a DNA match will be a real "light bulb" moment
but most of the time it is a hard methodical slog to make sense of the data now in your possession. I do urge you to "make haste slowly" pausing to find answers to all the questions you, ask yourself. (What does this mean? What are the implications of that? etc.). The isogg.org site is a brilliant free resource to answer most of your questions but within in is a lot of information.
Finally, unless your ethnicity results include Ivory Coast, Melanesia or the moon, they are of almost no value in North-West Europe.
And remember, when you get stuck, there is always Rootschat
