I have an F3P right here.
The seals are silicone and don't normally need maintenance, not much need to re-foam and all that. I haven't had to touch mine for any reason since I got it.
The shutter release is flattened and covered by a rubber cap. You may be remembering that the rubber cap can wear through, which is probably true, but mine is in fine shape.
The rewind knob lifts up to open the back for fast changes without fiddling with a lock/safety thingy.
The meter is active right away, you don't need to advance to frame #1.
The shutter speed knob is a tad bit taller, I think.
A bunch of frilly bits are gone.
It was half the cost of a Titanium model.
It serves well as a carry-about, takes to bumps and beatings well, both of which are personal opinions of course.
You wouldn't want to get one for studio work.
