I listened to them back to back and I'm still not hearing a close comparison. "Given to Fly" isn't even that hard hitting of a song for Pearl Jam so the only similarities I could give you would be that the intros are kind of similar, they have loud choruses, and comparable lyrical content but that's where it ends. The song structure isn't the same (Pearl Jam has a lot of louds and softs where as the Foos go from a building intro into a hard hitting song that never comes back down the levels of the intro), the overall tone of the songs are way off, as you pointed out (and not just lyrically but musically as well), and I would never compare Dave to Eddie as singers. A lot of the time Dave just sort of shouts and while Eddie can do that as well he has that certain....flow to the way he sings that has been getting ripped off for years. If I were to compare anyone to Eddie it would be Scott Stapp from Creed and that is ONLY because he completely watered down and bit Eddie's entire finesse for singing. It all comes down to the yarl that Eddie (basically) invented that Dave doesn't even dabble in.
