Looking at the reported bids, statements made, and probable finances behind them (I say probable, lets be honest the Qatar bid will have the financial backing of the state behind it regardless of what is said publicly), objectively the Qatar bid is the clear winner in terms of securing the future of Manchester United football club and being able to continually compete at the level the fanbase would expect.
Based on the little we know about either bid, it certainly appears that the SJR backed bid will add more debt to the club (whether against the clubs name or his own company), and without any clear indication of how that will be serviced, along with any meaningful detail on additional spending on infrastructure or 'other', whilst the more romantic option (Manchester born businessman saves us from the Glazers), realistically it carries a level of risk and doesn't give real confidence that we will be any better off in a meaningful sense compared to where we are now - and that's before you consider his age and potential uncertainty about any succession planning.
On the other hand, a section of the fanbase will clearly have their own views on the non-football related reasons why the Qatar bid is less appealing to them on a personal level and they are also clearly valid considerations. These are far more subjective views and will vary from person to person and are too numerous to do justice to by listing them on their behalf.
For me, as things currently stand I'd vote for Qatar as the new owners (and did on the poll), based entirely on the footballing side of things. If SJR went public and gave certain assurances on the things mentioned above then I could be swayed, but I seriously doubt he would be able to; my personal view is that there will be a desire for a certain ROI for the purchase to at a minimum service the debt, and then in the longer term profit from the purchase as a business that would see only minimal change at best from the ownership model we currently have and frankly despise.
This isnt a cry for a sugar daddy or to have more money than X club as some are portraying it to be, more to ensure that as a football club we don't fall behind as the game develops into what is obviously going to be an increasingly financially driven competition that started in anger with Chelsea, before City and Newcastle joined the race, and likely down the line further giants of the game succumb to.
