I'm in the same position as you. I was going to get a Como or a Signo for DH's car. I've been waiting for ages for these seats, and I'm not happy with the confusion over the RF issues. I know these will get sorted out in time, but I'm not willing to wait. I know the BV works in our cars. The main factor for me is my son's height/weight. He's 2 yo 8 months, 27 lbs, 34" and 13" torso, so in the BV we have plenty of RF time left (I expect until age 4), and then FF probably to around 6. Then I'll look at what seats are available then. Yes, the Como/Signo would take us FF past 6, but what I really need now is a RF seat. I also would like to see the RF como in my car in person to make sure DS could climb in it (higher up than what the BV is). I've driven DH crazy listing all the pros and cons, because both seats have them. I've decided to go with what will work for us now rather than what might/might not work when DS is 6. So, I got a BV from Baby Age.
You may differ depending on your child's height/weight, whether you can wait etc.
