It boils down to personal preference,Hania Beach and Sahl ar both at early development stages, Sahl is beautiful but it does have it's own problems with many developments well behind, and to boot not even one shop open here yet,however the location and exclusivety speak for itself.
A lot of the newer beach developments which will be released this year will have similar prices,you do have to look at what facilities the development will also provide.
We can't all like one development or one location it's a personal choice,what we do have in common is we have all invested in Egypt,What is not good now will come good in the future.In a few years we will all be wishing we had invested more and been less cautious.
