What to? or What to? combine Edge 1030 logs with Vivoactive 3

I was riding with VA3 for some two years, the graphs were not perfect in GC but for what I need (60 yo overall fitness) it was OK. I tried two Data Fields, the default cycling app and the JMG-DTF cycling app. Garmin speed/cadence sensors each set on two wheelsets (gravel and road).

Got recently the EDGE 1030 second hand from classifieds, I will be setting it up for riding in my basement for now, winter is knocking at my door any moment.

How can I combine the graphs or better which one to use in GC?
