We run Slackware in production and it works great for over 10 years.
I would run any commercial software on Slackware. The kernal is the same, the utilities are mostly the same. A distribution is simply a 'way to organize' and 'market'.
I trust Slackware as much or more than other Linux distribution. It has been around longer than other others and is very reliable. I have used Slackware since 1993, 12 years, in production environments.
However, many say that Slackware is not for 'newbies'.... I don't know because I had many years of UNIX (mostly HP-UX and SunOS) experience before I started with Slackware in 1993
I think you will be happy with any distribution!!
