The biggest problem with G+ was they replaced GChat, and Hangouts was emphatically slower than GChat. Maybe the G+ product itself was fast - the only part of the product I actually used was a huge downgrade from what they had before. I actually stopped using GChat for years as a result, just because it was so slow. Also I think Messenger may have been faster than Hangouts. It was not faster than GChat, but it didn't matter because Google killed it and that definitely drove me to use Messenger more.
