here's my 2 cents, based on having a problematic j pouch, which eventually i had removed for the k pouch. i had to have an ileostomy for a year after my initial j pouch surgery, due to a snafu, and even with the problematic j pouch i greatly preferred the j. even with the extra efforts w the k, i prefer it over the ileostomy.
another 2 cents and this is in absolute respect of this fantastic, helpful forum--for me it is family, generally--but not always--people who have problems participate, and subsequently you read about the small percentage of people who have problems with their j pouch. that makes sense as people who function perfectly well w their j don't even think of asking for advice once they have gotten over the initial decision. some people, such as richard, still participate, for which i am always grateful. as i said, we are family.
keep us posted on your decision. perhaps get more info from the stoma nurses as they often have make more time to discuss issues and often have more info. where are you located? that too can make a difference, sad to say in such a wealthy nation as ours..... be well, janet
