I kinda wanted you to give your opinion  on it.   How do you like it ? 
As a bomber guy (full disclosure, not currently playing the game), I voted the B-29 all the way through.  However, I loved the B-29 when I was using it.  It was expensive, added a little more danger to your missions, definitely forced you to fly them high.  My problem was never with the bomber, or with the perk price, but with targets to hit.
I had hoped that with the B-29 would soon come a redesign of the strat system.  Unfortunately, nothing ever came, and it was just not worth the time to take a B-29 up to 30k to hit city strat.  I still hope strat will be changed in a way that might make the B-29 a little more relevant, but I haven't heard anything that points to that.  I don't regret my vote for the B-29, but I hope there are changes relatively soon.
