I started with a wired Powertap. Then I got a wired SRM about a decade later. Replaced that with a Powertap G3. Then tried a Power2max. Didn't like that (because of BB30) and sold it pretty quickly. Then got a Powertap C1. That's worked flawlessly for years. Bought another PT G3 on another wheel, and last year bought a Quarq Dfour.
I would buy a Quarq, Power2Max, or even a used SRM if a good price.
Favero Assioma pedals look awesome, but I absolutely abhor the cleat system it uses, so no go on that front. Others without that hangup seem to really like them, though.
So anything that measures both legs. I wouldn't bother with anything that only measures one leg.
