These three models now make the most sense as legacy/value choices, not as the top of Tineco's current lineup. Buy the i6 Stretch when it is meaningfully cheaper, choose Stretch S6 when it is the best deal among the older Stretch models, and consider S6 Master only when its premium refinement comes at a small price premium. If you are paying current-generation money, move up to the newer Stretch Series or Master Series instead.
