Sounds like this is pretty solid, but here's my 2c anyways. If you know how to do it, I recommend a manual install. That way you know exactly what's happening, and you'll be more familiar with the process in case anything comes up. Softaculous is great, but if you have the technical know how I would install it yourself. It's still pretty easy, but yeah, will take a few more minutes that using Softaculous.
