Of course I showed those two boats to represent extreme fast paddle boat v. the Revo, which is the fastest pedal boat.
The stability, or rather instability of those two boats is also very similar. You have to sit higher in the Revo in order to pedal and, in that narrow 28.5" hull, it feels very unstable sitting still.
The Revo is also the one Hobie that's good at both paddle and pedal, though you may find the Outback and Compass acceptable when you need to paddle them.
Sitting up tall also makes you more susceptible to all wind factors, and my choice for 10-mi coast paddles and my over-60 tush is my T160, which sits low to reduce those wind factors.
I can put in a pretty comfortable fishing day with my legs dangling over each side, which you can'd to in a much wider boat.

The Hobie Outback, PA, and Revo all have two seat heights to adjust between, though I can't imagine using the Revo in the high seat position. The Compass only has the fixed low seat position, though for pedal, that position is still much higher than paddle-only boats.
What our OP really needs to do is catch an ACK demo day, to try a bunch of boats, and I think the best water to test boats is the San Marcos demo (they also sell there with a minor discount, and will really slash blem boats).
