Which KV? Some pictures would help. I recently saw a RR in the metal, and I was in awe in terms of finishings level. Both are great watchmakers, so it is not a criterion for me.
I think the main criterion is the " special " against conventional. Here, the RR wins.
And it is hard to compare a KV 28 for example, with the AK 06 which is a Tourbillon.
If you are more into a classic watch ,go for the KV. If you are more into something special, go for the AK 06.
