Queston on Garmin 73DV and 73CV with one of these trans ducers GT20 or GT22

I am confused on chirp with these two units, I have read articles and talked to Garmin support, but still confused. Does the 73DV give you chirp just in Down vu and is that a good thing. I was told the GT22 give chirp all the time plus clear vu, is that true and is that good. I think if buying one of these, I like to be able to use chirp and not use it. I am also looking at the 840xs and that comes with GT20 or can order without transducer. I appreciate any help on this issue.

    I am trying to make a good choice and now looking as these at Simrad G07 xse with navionics + or Lowrance HDS 7 Gen 3 with inland and coastal waters. Will order this transducer for either one as recommended 000-12570-001. Also in the mix is Garmin 840xs with US and coastal waters, GT20 transducer.
