The single biggest difference is the 7189's ability to handle higher anode voltage ~400V vs ~300 for EL84. Not good at Cyrillic but the datasheet that comes with the ER seems to indicate 450 or 500V on the anode and 14W. Regardless, I've used ERs in apps that beat the crap out of 6BQ5s and they aren't phased.
