absolutely not
Defiantly not so
Im not sure what you guys disagree with me about, but ill rephrase
in my numerous experiences, (ive driven each way around 15 times each), the 6 is a much faster ride, usually shaving 30 minutes off the journey (and since its a 2 lane for some time, if there are many pple going, such as on lag beomer, the 90 is a nightmare), AND the 6 makes for a much more pleasant driving experience especially if you drive with speed since the 6 is for the most part straight while the 90 is very curvy.
therefore, IF YOU CAN AFFORD IT, in my opinion due to experience, the 6 is a no brainer.
if you cannot afford it or looking to save money at the expense of comfort and time, the 90 is also an option and one shouldnt refrain from taking it due to security concerns
(i believe, and i might be wrong, that if the 6 was free, nobody would ever recommend taking the 90)
if you dont believe me aout the time saved, maybe you will believe google
