I prefer to remove. If I do leave the membrane on, I like to give them a good bottom sear post smoke to crisp the membrane.
A problem is ribs that have the membrane already "mostly" removed. If it isn't done well, then removing the remaining membrane is very difficult because it rips apart, etc. My ribs usually come from Costco. They are Smithfield, and the ribs have the membrane mostly removed.
In cases of partial membrane the only alternative seems to be scoring or ignoring. I've wondered if a stainless brush might help.
Like most everyone here, I can remove a full membrane quite well.
A more serious gripe with these ribs is bits of bone left from sawing. I rinse and try and remove all bits, but some of it is embedded and I don't detect it until later. Sometimes it is minor, sometimes more major. I know they run those saws at insane speeds, and this is bone breaking rather than clean cutting. That is a big headache and risk, but a discussion for another thread.
