I run several domains and subdomains on one NaxHost account. I have SSL on one domain, running OSCommerce.
I haven't had any big problems, I find them helpful on customer service, and uptime is as quoted or better.
Their server setup is very flexible for php, allowing me to set individual php.ini files.
I wouldn't have known that cPanel had been limited, because it has lots of useful functionality.
It's great value for money, and I'm a happy customer.
