It literally makes no difference at all, it will have zero affect on liquid under pressure in this application.

If its a custom loop, then its recommended to have the ports on top to get the air out.

If its an all in one cooler, then go with whatever looks the best.

It made no difference to me, I just lifted my case slightly... I'm yet to have a big issue with the orientation of rads, then again I always bleed air by taking a rad cap off then reinstall it before the coolant even gets close to the rad, I normally have to turn the pump off and refill a long while before that. Have you had issues with this? Just wondering is all.

If you have the ports at the bottom, so will air be trapped in the top and it can be very hard to get out (as you almost have to turn the case on its head, for it to move).

I had a 120mm as exhaust once and never had this issue, even if the rad was bigger it would make difference if you let the air escape with the method I suggested. If you have a weak pump then maybe I guess but I had a DCP2.2 once and even that had no issue removing the air from my 120?

Its just what I have gotten recommended, as I havent done vertical radaitors before.

No issues here, if you're smart about it you're fine, no matter which way you go about it. The worst part about it is how long it takes all the air to come out but I've yet to get the same result from both orientations, you can't remove all the air from a system in one go, doesn't work like that unfortunately.
