[FOSS-GPS] Quadrifilar vs patch? Choke rings?

I have a pair of quad antennas, and a patch.
I don't have a choke ring for either one, although I'm considering
building one, I don't have them now. I have a CNC mill and it would be
primarily an issue of getting aluminum billet stock.
Which is better for RTK? I was just told that the quad without a choke
ring may not be as good as a patch without the choke ring- in which case
I can use a pair of patches.
WITH choke ring designs, are the patches or quad antennas better?
The rover may climb a 30 deg or so slope at times. There will be some
tilting of the antenna.
