Don't know if this helps, but the way I take people through this debate is to ask them what they want to use it for. If they want a two person serious touring machine and/or a four person sightseeing/fun trip machine then the R44 will do nicely. If they need more than this then they need to think about bigger machines.
All the stuff about cyclic, reliability etc. is really just individual preference/prejudice. Of course the Jet Ranger is 'better' and as a result it costs more to buy and run ! But if the R44 does the job you need it to do then it will do it for (much) less. You don't really have to look much further than Self Fly Hire rates. Around £400ph in the UK for the 44 and about £500 for the JR. Knock £75 or so off these for profit and you can see what 'on average' they're going to cost you.
Oh and if you're thinking about buying, remember the three Fs.
