those are the same graphs ive managed to find today .
1: the 109 is superior in roll rate below approx 280mph (ias or tas not specified), comparable in the 280-310mph bracket, while the spitfire is marginally superior above 320mph
2: Unless im reading the legend wrong, kinda a rough image, the spitfire and hurricane are comparable in roll rates at IAS of 200mph and above.
experience for me thus far is the hurricane is 30-50% slower in the roll at various speeds above 200mph to the spitfire.
the subjective accounts are varied, the one you quote contradicts other accounts.(and the images posted)
