I think you're making the right decision. For that price on the bow you can't beat it. I haven't seen a Tribute around here for less than $679. The difference in noise is irrelevant if you ask me. In my opinion I would go with the Muzzy Zero Effect Next Gen on the Tribute. I put one on my Allegiance last year and I loved it. I'd have one on my Guardian right now if they had a model that worked with these bows. The MZE took about a half hour to install. Hardest part was installing their provided cable slide. Once that was on the final install was a breeze. I like it because there are no cables to worry about and the rest never makes contact with the shelf like most other drop aways so you don't get that little slap on release.
