I guess I fail to see what benefit methodology could do for laymen such as ourselves. By making Taqlid of Ashari/Maturdi you're taking in some pretty complex, heavy handed, somewhat controversial details many of which can't be summarized. I could understand if a scholar well-versed in Islamic scholarship and theology delved into that stuff, but I fail to see what usefulness such a HEAVY, controversial subject would be to laymen living in these times when 99% of the world populations couldn't care less about theology.
The era of theological debate which was prevalent amongst the Greek Byzantines/Mutazalite societies no longer exists. During those times many scholars basically used a lesser, minor biddah to combat the major biddah perpetuated by the Philosophers and the Mutazalites. The means the Muslim theologians used were controversial, but somewhat understandable given the immense power and violent methods the Muzalites employed at the time. So even though they may have played with fire; we can be sure that they were well-intentioned because it was done in order to combat the greater evil spread by the heretics. So InshAllah they will be forgiven for the unorthodox methods they had to use to combat the greater fitnah.
But in today's times there is no need for Muslims, especially laymen to burden ourselves with such a complex, controversial topic especially when we have so many bigger things to worry about and very few powerful people in this world place any emphasis on theology. So let's just stick to the Qur'an and Sunnah and use these to unite and strengthen this weak, disunited Ummah.

Regarding modern-day Sufis, I'll admit I'm a bit bias by all the vids I see of prominent Shaykhs such as Habib Ali Jifri dancing in the Hadra; but maybe I ought to check out the more conservative Tariqas
