how about sitepad now ?

I’ve no first hand experience of SitePad, but what I will say is that anything I’ve used by the Softaculous team has been great.
Checking into SitePad specifically, I see it still gets frequent updates (always a good sign). Their tech support is decent too so I’m sure if there’s any issues they will happily help you work them out.

I also see they allow you to request a demo on their website, so why not give that a go for yourself and maybe shoot a link to a couple clients and ask for their feedback too.
