No that is not the consensus at all. You are hearing from a vocal group of people who sadly have had troubles with El Capitan for one reason or another. There are many of us who have had no trouble at all, but we don't make threads to announce it.
*********
I read every post you write Weaselboy and respect you very much.

However I honestly do not believe that the great number of bugs and problems reported since El Capitan was released can be purely explained by your repeated theory that ONLY people post when they have problems and those with good running computers don't.

Whenever I post a problem I
emphasize that with the same hard- and software I did not have that problem running Mavericks and Yosemite.
I have no
aversion whatsoever to El Capitan. It seems unfortunately less finished on release that previous OSX were.
Both myself and other users with problems appearing only in El Capitan running computers
must and
should be believed.

People complaining just for the sake of complaining are very, very, very, very few sick people!
"Une quantité negligéable"
Those telling about TRUE problems are by far the rule.
If the number of bugs reported reaches the high present level it is NOT necessarily because MANY MORE ENTIRELY HAPPY USERS OF EL CAPITAN KEEP SILENT.
As far as i know
YOU belong to this happy bug free users, but this does not solve the problems of the
MANY YES-BUG SUFFERING USERS.

Actually
NOT EVEN APPLE can tell the percentage of success and that of failures with OSX 10.11., now
ALREADY IN ITS
second correction which
EVEN HAD TO INCLUDE A REPAIR UPDATE TO THE RECOVERY!
I do not see that as normal and still AM POSITIVE that Apple
SHOULD had included the 2 updates and the Recovery correction in the final release of El Capitan to the public, which came IMHO
much TOO early and much TOO unfinished. 
Waiting a few more weeks would have done no harm to anybody and on the other side had prevented very many problems and frustration to a lot of Mac users all over the world.
