Crap shoot currently.
Have a board with Gat clears, zealios but undercut by gateron who make zealio,s only ran for a short time before zeal asked them to stop selling his switches for half the price.
Have a switch tester with an MX clear. It is not too scratchy really. At least I do not notice it at all when switching between my linears of both cherry and gateron, I have to actually focus on it to notice and then it is gone again the minute I stop looking for it.
The crap shoot is Cherry finally replaced their moulds so they claim they are good as gateron again. Just not sure if they got round to the clears yet, or even if you can specify new batches when ordering them yet.
It would not be worth it for me. But they are smoother, just not enough for me to warrant the extra price of zealios.
The Gat clears were 50cent per switch compared to zeals at 1dollar so that was worth it.
However if you are going to be taking apart the switches before you install them you could lube the switches with some krytox, that would make them the same at the cost of time.
