Do these four Sources of osol-al fiqh have equal authority?

The four fundamental sources of the osol al-fiqh I heard are - Qur'an - Sunnah - consensus of Muslim jurists (ijma), - qiyas (analogical reasoning) **a) Do all four of these sources, have equal authority, or one prevails over the other?** For example: 1. Qur'an 2. Sunnah 3. consensus of Muslim jurists (ijma) 4. qiyas (analogical reasoning) **b) Do most of the scholar accept these four Sources?** For example: Ibn Taymiyyah opposed the use of consensus of jurists, replacing it with the consensus of the sahaba. --- Reason of question: I see some question on this site, regarding the scholar view even though there is clear Quran/Hadith indication, so are the scholar views at par with Quran/Sunnah.
