Which do you like better, chess870 or chess960?

You have to move a rook on 1 side to castle on the other side (assuming nothing captures that rook you have to move or anything) in 90 out of 960 positions. Are you ok with these 90 positions? Or perhaps you prefer chess870?

Like Rf1, Kg1, Rh1, where the rook on f1 has to move in order to castle kingside. I am fine with these positions.

I feel dumb but I don't understand what's the issue here
