My guess, if you are finding it complicated and downloading hundreds of different brochures, is that you are approaching it from slightly the wrong angle.
It is easy to think that you have a genuine 'choice' from all the schools available - in fact in many ways that is encouraged by much of the information out there - and thus you need to sift information about all schools to find what is 'best' for your child, thinking that you need to decide between 20 or 30 'outstanding' schools...
In fact, in most cases there are really quite a small number of schools where you have a realistic chance of getting a place. For many people, there is only 1 school actually in this category, though in other cases there may be several where you have a chance, or 1 main one and some where you have a small-but-still-possible chance..
Unless you meet very specific religious criteria (Catholic, usually, though some CofE as well), then your nearest schools are those most likely to be the ones you have a chance of getting a place.
This site www.schools-search.co.uk/ will give you a list and map of your closest schools if you enter a postcode, as will www.gov.uk/find-school-in-england though for some reason it won't accept my postcode when I tried it.
Your council booklet should then give you details of the over-subscription criteria for each school. Some councils, though not all, have further information about furthest distance admitted or number of children admitted under each criteria. If this isn't available, then you may well find it elsewhere - www.whatdotheyknow.com often has the replies to similar queries from your area.
This will give you one or more schools that, from past history, someone living in your house would have been given a place at.
Read the Ofsted reports for and visit the schools that you work out you have a realistic chance of getting into, to decide which you put first on your form. If your first choice is a 'with luck and a following wind, in some years I might get in' one, then make certain that your list also contains the 'nearest to a certainty' you have available.
If your initial 'distance' search either throws up no schools you would usually be admitted to (it does happen) OR none that you are prepared to consider, then you need to identify schools further away that did not admit right up to their PAN in previous years - again, many council booklets will contain this information - e.g. PAN 60, admitted 58 - and a) work out whether you can physically get there (you won't get free transport UNLESS this is genuinely the closest school which could have had a place for you - e.g. if you ignore a bad school with spaces 1 mile away and apply for one 4 miles away, although 4 miles is over the limit for free transport, you won't get it because you COULD have had a place in the 1 mile away school) and b) which of them you would be prepared to consider. Undersubscribed schools are usually undersubscribed for a reason - which may be as 'unsinister' as 'geographically remote', but could be a history of very poor performance.
