Propstream or Batchleads which one you prefer?

[Omayra C.]

Hello, I am trying to put together a list of multifamily owners. At the moment I have batchleads and I can use postcards to market but there is no way to customize the cards, the only thing you can do is change the text and phone number.  Also it seems as if I get a smaller list when I do a search than any other sites such as listsource. I was thinking of switching to propstream but would like other users thoughts. 

 Can anyone share their thoughts and/or their success with either one?
