I do not know her playing very well, but I have enjoyed all the volumes of her Beethoven piano sonatas released to date. The character of her playing suits that of Beethoven's music. She doesn't have the technical control of a Yuja Wang or Hisako Kawamura or Steven Osborne, but then nor did Friedrich Gulda or Alfred Brendel, the artists she most closely resembles from an aesthetic perspective. The energy and freshness and attention to detail already makes her cycle superior to those by e.g. Barenboim or Kempff or Ashkenazy. The main deficiency of her playing (& that will most likely keep her cycle from joining the "great" ones) is that it is small-scale; she doesn't bring out the long phrases, on the 16- or 32-bar level, and how they flow into one another. Her phrasing is choppy. At times this doesn't matter too much, e.g. her tempo in the first movement of the D major sonata Op. 10 no. 3 is fast enough (minim = ~158-162, which is more or less correct) that entire sections can be played as more or less one long phrase without needing to bring up distinctions between them. At other times this is a bigger problem, e.g. in the slow movement of the same sonata phrases feel disconnected from one another, and there is not enough coherence to hold a listener's attention (me being the listener), or to maintain the shape of a broad dramatic "wave" building inexorably to a crest in bar 72 and then breaking.
(It might be helpful to compare Lisitsa's performance of Op. 10 no. 3 to the greatest one I know of on record, which is Martha Argerich's from her set of early recordings on Deutsche Grammophon, to get a better idea of her strengths and weaknesses. Argerich plays the Presto at around minim = 152, which for Beethoven was more of an "Allegro molto" than a "Presto", but in all other respects shapes the first movement much better with respect to phrasing. In the slow movement there is obviously no comparison.)
I would overall therefore consider Lisitsa about as good (in Beethoven, anyway) as Gulda or Brendel, or Yusuke Kikuchi, Stewart Goodyear, or Michael Korstick. IOW, part of a large group of technically and artistically proficient pianists whose playing can successfully convey the intentions of the composer, if not actually realise those intentions. There are pianists who can completely realise a composer's intentions, and there are pianists who can go beyond the composer's intentions altogether and present their own equally valid interpretations; Lisitsa doesn't fall into either of these categories. But I think she's significantly better than average.
