Yes, I did... as you can see in my signature, I own all those handheld antennas...
The deluxe performs slightly better than a stock ducky on VHF/UHF, other than that nothing special.
I did a lot of switching antennas around on my 2 scanners, and currently my 97 is with the RS 800mhz and my 83 is with the RH77CA. I found that the RH77CA is even better than the deluxe on VHF/UHF, but no HUGE difference...
Positioning is much more important.
