I recommend it. I did a three man trip in the Seneca in June. We liked it a lot, although we felt ridiculously huge out there, both in length and width. High stability, but somewhat slower to maneuver.

Plenty of leg room if you don't have to stow a bag behind the middle paddler's seat.

All three of us are about 6', 190, so we rotated seat positions without concern for weight distribution. Stern seat was best for fishing. All three fished at the same time.

Reach from middle was longer, but still comfortable.

Stern seat was too narrow to fit a SitBacker chair, but it worked well enough upside down.

Three men paddling can generate excellent speed and save energy, but only if you're synchronized. I sometimes get annoyed sitting in the bow while the other two guys are happily paddling willy nilly. When I'm in the stern, I encourage the middle guy to keep time with the bow paddler, then we start gliding smoothly.
