PM5 Rower connecting to Fenix with ERGIQ vs Garmin direct connection. What is the difference?

PM5 Rower connecting to Fenix with ERGIQ vs Garmin direct connection. What is the difference?

Is there any difference in the data recorded when using ERGIQ vs using the new garmin rowing connection feature? 

For example, does the garmin connection give you V02max information and ERGIQ doesn't? What about training load, etc. is the data recorded when you do a ERGIQ workout on fenix 6? 

Would be great if somone from Garmin could give a full comparison between data and metrics delivered with garmin rowing connection, vs ergiq.
