I've got two pairs of Assioma Duos (with SPD hack) and a pair of Assioma Pro MX (comes as SPD). Oldest set is 5 years old, and still works fine.

The Assiomas are consider as accurate as any other power meter. And I are one of the most affordable. Very well made and just work.

They had a safety recall on one of them. Though I had no problem. I filled out a form, they sent a complete replacement pedal. Activating the new pedal, disabled the old one. Can't complain about a company trying to stay ahead of an issue and fixing a problem I didn't know I had.

Last year I swapped all my cranks out for shorter ones, using pedal based meters was a big win for that. I can't think of any downside with these for road riding. There's some concern using pedal based meters for MTB. But I have done that without issue. But obviously pedal strikes are common with MTB rides so there is some potential to damage them. But the pedal bodies and be replaced like any pedal, and while I'm sure some riders have bent pedal spindles, I don't think that is common.

The older Duos I have, have the electronic pod on the side. This could interfere with using MTB style shoes (again with the SPD hack). But the Pro MX and the newer road version, have all the electronics in the spindle. Nothing large a chunking sticking out. Only issues with this, is you cannot use them with pedal extenders to increase q-factor. Any extender will cover the end of the spindle and block the radio communication of the pedal.
