Okay, first of all... "I really need backlighting (white or red)." - nobody really needs backlighting. If you can't see the keyboard legends your general lighting is too low and you're not doing your eyes any favours. There shouldn't be a great contrast between your screen and the surrounding area as it causes eye strain. Long term it can cause other problems.
If you still want backlighting, then continue reading:
Well, you've got a good selection right there in your OP. Any one of those should make you happy. I prefer Cherry stabs, so my choice would be the Ducky, since I find Costar to be more rattly, fiddly and they don't play well with some thicker caps due to the bar rubbing on the inside. If you don't like the bottom-out feel they can always be clipped, although it may require some soldering to do. If you want Costar stabs, the Code and Varmilo both use those.
The Rapid-i is another option (with Cherry stabs), but I'd hesitate to get the Corsair since it doesn't have a standard layout (and it has a 6.5x spacebar), so getting replacement keycaps is high on impossible.
