I have an yearly basic subscription with PacktPub Mapt and I am supposed to read books and see videos. My subscription is valid until Feb 2019. However, on July 2018, I was suddenly not able to see videos or read books. There is no option in the website to rais a support ticket. Only option available to try was to send a mail to the email email@example.com. I even tweeted to them.
We have been using Site5 for past one year, mainly for our sites under development or beta stages. While their speed is not the best, it is still not the worst. Definitely we could not find it lightning speed as they have named their best plan.
One thing we liked about the plan was that you will get a separate cpanel for each of your sites. This will help you a lot if different developers are working on different sites.
Also, one thing we liked about Site5 was that, their ticket based support gets back usually within 24 hours max.
Bluehost is one of the very old providers we have tried. It used to be very good initially and due to some bad experiences with uptime, we had moved to another host. With their recent improvements, we decided to give them chance again. But looks like things have become worse, not just in performance but with their support as well.
