All jokes aside, it IS both important and very much relevant to include them when you are discussing the 2 player's NT repertoire, both in terms of accomplishments, and in terms of direct rivalry.
Boskovic for sure has the better record in ECh, but what I wanted to express in my original comment is that although Egonu was showing signs of maturity in 2017, she really matured in 2018 during the WCh and developed into the player she is and it's about how long they've played, not who won what.
My personal opinion is that Boskovic has been playing at a high level on the NT since 2015 even though she is still improving. For Egonu that's 2018 onwards.
So I think comparing "consistency" between Boskovic who's been playing at a high level since 2015 (with six major events: 2015 WC, 2015 ECh, 2016 OG, 2017 ECh, 2018 WCh, 2019 ECh) and Egonu who has played two major events (2018 WCh and 2019 ECh) is kind of pointless. You can talk about the consistency of Boskovic's performance, but for Egonu there's only been two events, so....
