PCI vs PCIe vs PXIe for behavioral computer

I'm looking into buying my behavioral/control computer for my rig and I'm wondering if MonkeyLogic prefers PCI vs PCIe vs PXIe computer ports? The rest of our setup will consist of eye tracking, joystick tracking, photodiode, and neuopixel recordings.

The NI Multifunction I/O Device page in the docs talks about this a little bit, but I'm not sure if there's a preference between the 3 options.

The bus type matters only to you and your computer, since there can be some price difference and your computer may not support some bus types. NIMH ML does not care, as long as the board is supported by the current NI-DAQmx driver.
