Thanks for putting up this poll, Bobber! I'll fill it out as soon as I've heard all of George's solo albums. I've heard most of them now, but I'm still filling in my gaps. Considering I'm a relatively new fan, I hope you'll forgive the delayed response. I want to be accurate!
I think around the time of Concert For Bangladesh he was just about the biggest star on the planet, but never really capitalised on it. But then he's always come over as a reluctant star, so maybe he wasn't that bothered.
It's so hard to tell his true feelings about this. According to studio notes I've read--George Martin, perhaps?--George was astonished by the success of ATMP. He set about to make an album of stuff he was personally interested in, such as Krishna consciousness, and never in a million years expected anyone much beyond the devotee audience to particularly care. As for his secular tunes, like "Let It Down" (which is a personal favorite of mine), he'd already been assured by Paul and John that these songs were unworthy for inclusion on a Beatles album, and they ought to know when a song is lame, right? So he made the album basically as a labor of love, and it shows.
As far as Bangladesh, I have the DVD of that concert. In the extras, George is being interviewed with Ravi. I believe this takes place a week before the concert, as that's when he announced it. Anyway, he is clearly astonished (and terrified) that the tickets sold out so fast. Some guy says that the love of the Beatles seems to have been transferred to Harrison, and George acknowledges that appears to be true, "but I don't know why it should." Apparently in George's mind, Beatles and GH were so separate, why would the rest of us lump them together?
So (as he later acknowledged himself) he never set out to manage his career. He acted from the heart, just to get out his songs (basically for himself) and then to help the refugees (for Ravi). By the time he figured out he was a big star on his own, he probably had no idea what to do. I imagine his early success went to his head and he thought he was just extra lucky or something and could do whatever he wanted, and people would love it. Then again, he was always waging spiritual war with his ego, which probably clouded his judgment when it came to achieving commercial success. It's really tough to say.
