 Grigoriy, Yury,
 Nice book. Try also: "The ABC of DFT" by Kieron Burke et al. This is a
 free and excellent book written from the point of view of physicicts.
 emember that in DFT Physicits and Chemist finally found a true
 conection.
 Once a year we receive information from ¿Girona, Barcelona? (Spain,
 anyway) about which functionals perform better for each kind of
 property. The basis of that report is that practitioners vote their
 preferences. In young Internet times it was assumed that market, social
 media, whatever in which a huge amount of people participated was a true
 way to discovery. The finantial crisis has made evident that such a
 trick has many problems, but .... You can check. In the Girona polling
 only quantum authors participate, if I remember correctly.
 Look for Prof. Marcel Swart at ICREA. The 2017 results:

 Marcel,
 Do your poll includes solid state properties? Many physicits participate
 in the poll? I just don't remember.
 Cheers,
