I have intermittent issues with Opera (logging in -- account not recognized; and modifying reservations-in-progress). I can usually cure the login issues by opening up a developer window (Ctrl-Shift-J in Opera) and doing a shift-reload to bypass the cache. Once in, I can close the developer window. Opera is not a true clone of Chrome but they are similar and share some common components.
Otherwise I've found that Edge is usually pretty stable and reliable.
