All things being equal (or more or less equal), go for the lightest wheel that fits your budget. Winner: Assetto Gara, by a country mile.
If you are swapping the OEM tires over, the 17x7 Assetto Gara will be a better fit vs the 17x7.5 Pro Corsa. The OEM tires fit very well on 7" wheels and will be a bit more stretched on the 7.5" Corsa. Winner: Assetto Gara
OEM Wheel specs for reference: 17x7, ET47.5, 63.4mm Hub, 22.5 lbs
Full disclosure: I am so completely biased against heavier wheels I cannot find any reason to recommend the Corsa (I upgraded to 16" wheels for weight savings personally). If you MUST have the 7.5" width, because you want to fit a wider tire (e.g. 215, etc) try to find something lighter.
Recommendation: Assetto Gara. I would not consider Corsa as an option.
Wise of you to ask advice, my very first aftermarket wheels (decades and many cars ago) were too heavy and I regretted it.
