I have both watches but I must say that if I had to choose one, it would be the reverso. To me, it is more special than the tank as you can engrave on the other side (I plan to pass mine to my daughter - so have engraved my "words of wisdom" on it). Plus the reverso wins hands down in terms of watch movement.
I was thinking that myself - it would be nice to give it to my daughter some day. My husband thinks he prefers the Tank but hasn't seen me try the JLC on either. He himself wants a Reverso Duo one day, so maybe he's just jealous that I'm getting one before him.
