Thanks everyone for the great input... I have zeroed down to Tableau; and will shortly post my reasons for doing so. I DO hope they will help future products selectors. Regards pete

Dear Peter, Your analysis is so ever helpful. The imaginary TCO as broken down is quite helpful too. Will definitely incorporate your insights into my final analysis. Thank you.

Thank you so much for the responses. Quite helpful in various ways. I sense a favourable leaning towards Tableau, will continue on due diligence keeping all the advice in mind too. regards Pete

Thank you for your insights. I have done some due diligence. I am however averse to "cost creeps" once my client has gone either way. The less the setup costs for instance the best for me. Or even if present, I would rather have an upfront cost estimation than one that…
