Is 2015 really that bad?

Howdy,

I've recently read a few different forums posts by users in different threads that say there are some pretty bad problems with SW2015.

I expected a few complaints about it being "buggy". But, one poster went so far as to call it a disaster.

Can ya'll start a list for me as to what is so bad about 2015?

We are about to upgrade and would greatly value your input.

Thanks.
