Designs are different, obviously, but it's the arraignment of the roof and roof supports that I see as what's important.
If you're going to go the retractable route you need to be willing to toss in the extra cash needed, even over a typical retractable roofed stadium, to ensure as much of the roof as possible isn't within the site lines of the spectators and pushed back as far as possible.
Chase field has it's roof looming over both sides of the stadium even when open and the supports out beyond centre field are in clear view, the fans are boxed in.
If they had lowered the outfield roof supports to sit below the stands and had the roof sections slide over more to open up the sky it would have been a very different feeling park.
I suspect the cost of doing something like that would mean hundreds of more millions.
Safeco is open air even when the roof is closed, that probably made it more feasible to have the roof arranged the way it is, it slides to right field on a 45 and sits well back, plus there's no visibly clunky supports needed all around the park, it feels open and looks good because of that.
