Hey Dan,
I've had my neobladder for 2 1/2 years, and if faced with the same decision today, I would make the same decision without hesitation. Done properly by an expert, a neobladder can provide excellent quality of life. I'm continent day and night (unless I have one too many beers too close to bedtime). I hike and play tennis and lift weights (and never wear a pad). I'm one of the fortunate ones who has near-normal erections without pills or shots (my bi-lateral nerve sparing surgery worked pretty darn well). Certainly there can be complications with neobladders (intestinal blockages - which I had), but that would not change my mind.
That said, others urinary diversions can be entirely satisfactory. Your choice of pouch will be limited by the repetoire of your surgeon and may be dictated by what he encounters during surgery. Frankly, if I had ended up with another type of diversion, I would have been pretty satisfied.
Keep in mind that one of the criteria docs check before moving forward with a neobladder is the patient's ability to comply. For example, patients need to be able to void often enough so that they don't end up with a floppy or ruptured neobladder (most void by the clock during the day every 3 hours or so, and at night one needs to be able to get up once to void). Plus there is effort required early on to gradually 'train' your bladder to increase in volume. All very doable, assuming one is not frail and elderly or has other limitations.
Good luck on your upcoming surgery.
