Probably horses for courses. Inno was the first I tried on 32-bit windoze back in win95 days after toying with WISE on win3.1, heh.
It comes with an optional 3rd party GUI tool (ISTool) as part of the Quickstart Pack download which makes it _very_ simple click-click-click to build a (basic) installer.. but for me, the scripting is far simpler as it uses a Pascal engine (NSIS seems more like ASM, which I haven't looked at since 16-bit days). I didn't know any Pascal previously, but as it's very similar to Delphi, which in turn is just like backwards C++, picking up the basics wasn't too difficult. All the tools I release are packaged with Inno and 99% of the time simply use the point-n-click options within ISTool to create them. I Only really touch the scripting area when I need to create something a bit more funky.
Agreed on this. Being a FreeBSD "fan".. I'm more than happy to work with archives.. but an installer does add some elements of professionalism and simplicity (for the most simply example, shortcut icons and a simple uninstall method without requiring the user to dig into the filesystem.. we all know what some (l)users can be like).
I'd be happy to share the .iss script file for Inno that I used to build the installer I did some time ago or even sort out a pre-compiled version (as well) if wanted
