Chrome's features like private browsing and tab/bookmark syncing are nice, but the defining feature of the brand IMO is that it is a very fast web browser. By linking the name to an app that will always be inherently slower than Safari on iOS, the brand is lessened with no significant upside.
I understand their desire to allow Chrome desktop users to have some meaningful interop between their desktop and mobile browsers, but I think they would have been much better served by not pretending this is an actual Chrome experience (much in the way Firefox allows some interop but keeps the distinction clear).
