Eco Drake / Eco Promenade in basement?

I apologize if this question has been asked before.

I'm looking to replace the toilet in the basement of my 1930s house (i.e., old drains, likely iffy venting). I was wondering if either Eco Drake or Eco Promenade will flush sufficiently well down there or if I'm better off using a bit more water with the "non Eco" versions? Any opinions?

Thanks!

It should work just fine.

The flush only last three seconds, and the water flows quickly down the line.
