i have 2 smart trainers, and a power meter on my bike.
Inconsistencies between meters, and unreliable data, are extremely frustrating. Very quickly, it's worse than not having power data in the 1st place.
Also, and rather shockingly, the Pogi interview on Attia's podcast has Pogi say he basically trains with HR because the shimano power meter is so useless that it can't be relied upon. That's insane when you think about it, given that the likes of Favero have been flawless for years.
Anyway.
My point: unless there's a major price arbitrage, i'd stick with options that are tested, with warranty and support. Saving 100 eur (random number) on something like that can end up creating so much frustration that i'd be careful.
