At the risk of TMI, I have been orgasming from a young age, so yeah, you could say that retaining the ability to orgasm was paramount. I wouldn't eat my gun over it, but it was extremely important. In the end I chose meta for a lot of reasons, the main ones being for me it was a 1-step surgery, low risk of not orgasming, lower cost, and closure of the hole.
I can honestly say that my orgasms are still excellent. They have changed somewhat, though it has been too long since before to tell you exactly what, though. They are still very intense.
I will say that having gender-normative junk, even if very small, has made a HUGE difference in my psyche. Yes, I can pee at a urinal, but mostly sit (peeing at toilets requires more control and if I'm not careful I can create an embarrassing situation for myself). But reaching down and feeling penis and balls is something I dreamed about since I was 4 years old. Seriously.
That said, I'd defnitely choose a surgeon with a good track record.
Edited to add: yes, post-op results can look fantastic, but remember that took YEARS of procedures and healing time to look like that. Look at all the top surgery pics floating around. Most are from 1-3 months post op, and fewer 5+ years out. Healing changes a LOT.
And my tiny dick, FWIW, passes physicals.
