Our recommendation
Buy the Angelbird for long-take video where its maker-rated sustained write and Stable Stream design are the spec that matters. Buy the ProGrade for mixed photo-video professional work, Refresh Pro fleet health management and typically easier availability and pricing.
Sustained write philosophy
Both guarantee V90, but Angelbird publishes a much higher sustained figure - in the 260 MB/s class - engineered to stay flat across the whole card. ProGrade guarantees the V90 floor with high peaks. For codecs near the floor both are safe; for the most demanding SD video modes, Angelbird's published sustained margin is the tiebreaker.
Ecosystem and support
ProGrade's Refresh Pro health monitoring suits teams rotating dozens of cards. Angelbird counters with in-house engineering, free data recovery service and a fiercely loyal cinema user base. Both out-support the mass-market brands; the flavour differs.
Price and availability
ProGrade is typically easier to find in stock at major US retailers and frequently discounted. Angelbird stock is thinner and pricing firmer. On a deadline, availability is a feature.

Questions, answered
Is either card overkill for photography?
For casual stills, yes. For 20 to 30fps RAW sequences on flagship bodies, both clear buffers fast enough that the camera, not the card, becomes the limit - which is the point.
Which is better for the Panasonic and Fujifilm high-bitrate modes?
Both are on those makers' recommended lists in V90 class. Angelbird's sustained margin gives extra comfort in the very highest All-I modes.
Do both work in UHS-I slots?
Yes, at UHS-I speeds, like all UHS-II cards. The investment only pays fully in UHS-II bodies with a matching reader.
