You're confusing wrappers with alternatives. The comparison is more like if somebody published a script called html-to-pdf.sh which directly calls, e.g, chrome, would you want to use this script or use chrome directly? I would prefer the latter because (1) I would know what actually does the conversion, (2) I would know what to search for on the web should I need to tweak the output. This knowledge gives me more power as I know the actual converter. The wrapper script perhaps only helps with what the command line should be.
