I thought I'd dredge this a little having just put T4V4s (220/203) on a full fat ebike that also has a kid's seat and 16kg kid on it a lot of the time.
I'm super impressed with the Hopes. I need to do a bit of a piston massage to get them perfect, but even putting them on in a hurry in order to pick up the kid from kindergarten, they bled up fast and easy, immediate power, no faff. The fact Hope ship brakes with multiple sets of pads is a nice touch.
The modulation is very good. I can't compare direct to Mavens, but I think they feel better than the Radics I have on another bike. Slightly longer throw, but much more lever feel.
I may be wrong, but the hope build quality is so much nicer that sram and I expect them to prove much more reliable that the usual sram shitshow of unpredictability and 'we're never seen that before' faff.
It may be worth adding that both the Radic and Hope bikes were using TRP DHR evos, which I found to be really shit. Even getting them super cheap I couldn't justify keeping them. Power was average at best, I had a first set where pads were contaminated with pad back plate paint which ruined rotors, and I swear the 2.3mm rotors mine came with were just never very good. I also found it really annoying they have designed a brake that uses shimano mineral oil, pads, and hoses, but not a shimano bleed bucket thread - their own one is forever out of stock. I think if you got a set suepr cheap and could run them with a different brand rotor and pad (maybe saint lines) they'd be ok.
