Rereading your post through the eyes of a thoroughly cynical former corporate drone, what in the world makes you think company B would be a good choice for you in your career other than the hiring person swearing he really wants you? (Before he has your career in his hands, which makes you a slightly less scarce and valuable comodity.) You're currently in a company where you are behind on the pay curve and can look forward to larger raises to get caught up, your company has gone through the downsizing period, you are doing real work that this and other companies will value, the other company just got reverse acquired AND you would be at the top of the pay range for your position? I've been through acquisitions and reverse acquisitions. You don't want to go there because the music will stop and there will not be enough chairs. You've been with company A for 8 months and you're already looking because you're disatisfied? Stay a whole year and then start planning the next step in your career. If you think longer term is more than six months your career is going to real drag on in about 5 years. Or ten. 20? 30? How old are you?

Stay where you are. Look for something better if you must. Company B isn't it.
