I spent over a year researching, talking to post-op guys, and talking to surgeons before making a final decision. You can read both of my bottom surgery adventure threads to see my thought process during that period.
Everyone I talked to led me to believe that phalloplasty was the best option for me. But being honest with myself, assessing my own needs, looking at the financial aspects of it, figuring out the pros/cons of having surgery now versus waiting, and considering some other factors obviously led me to the opposite conclusion.
Bottom surgery is goal dependent. You have to be honest with yourself about what exactly you are looking for as an end result that will make you happy, with the understanding that there is a high degree of risk involved and that it may take a while to get to that final end point. All I wanted from surgery was an aesthetically male looking package, no vagina, and to pee out of my penis (ideally standing, but that wasn't a deal breaker). Ultimately I decided to have meta done based on those desires, with the added caveat that I was completely open to going back for phallo in the future if my needs changed or I was unsatisfied by my results.
For me, an added benefit of meta is that you have that room to be wrong. There is never a situation where a meta patient can't go back for phalloplasty at a later date if they aren't satisfied with their outcome, didn't make the right decision in the first place, or if their goals changed over time. But if you are unable (due to age, health, life circumstances, etc.) or unwilling to say that, I would cool your heels and really dig into what is going to make you happy in the long run. I consider myself to be lucky to be in a situation where I can afford to be incorrect about my decision, as someone who is young, healthy, and has a large disposable income. Not everyone has that luxury, so that's another thing you need to be honest with yourself about.
All that said: phallo has come a long way in a relatively short amount of time. There are new innovations that are popping up all the time. Complication rates are decreasing as more surgeons do these procedures and figure out what works best. I have yet to meet someone who is completely post op (complication free, not planning any additional procedures) who is unhappy with their decision to have phalloplasty. I know many meta guys who go on to have phallo for a variety of reasons, and I know many who are completely satisfied with what they ended up with. Almost everyone waffles back and forth about which procedure is right for them.
Personally, I'm happy with what I've got. It works great, looks great, I'm complication free, and I'm able to stand and pee. I currently don't see myself going back for phallo, but I feel much more comfortable with the idea of it now that I'm post-op. I don't think I would have been mentally ready for a phallo recovery at the time I had surgery, but I think I could do it now having gone through meta. If that makes sense.
