The short answer
Based on available data, the Tesla Model S comes out ahead of the BMW i7 on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Mixed sentiment with a clear divide between strong appreciation for its luxury, technology, and driving experience, and significant criticism regarding its styling, market reception, and specific reliability concerns. The vehicle is consistently praised as a "luxury powerhouse" with an incredible, comfortable, and spacious interior, excellent sound systems, and a surprisingly capable and smooth driving dynamic that isolates occupants from road imperfections. However, it is frequently described as a "monumental flop" in terms of sales, leading to massive depreciation and deep discounts on new and used models.
Best version to buy
Insufficient owner data available to designate a specific best version. Commentary mentions the i7 M60 performance variant and the availability of an executive package with a large rear screen, but no consensus on a preferred trim emerges from the data.

Long-term owners of older models (specifically pre-2021, with mentions of a 2015 model) report severe dissatisfaction with long-term reliability and ownership costs, describing the vehicle as poorly designed for longevity with frequent, expensive failures. In contrast, discussions of newer models (post-2021) are more focused on competitive positioning, with feedback indicating they are perceived as technologically capable but lagging in interior luxury, build quality, and overall refinement compared to newer premium electric vehicles.
