I've had all 3 basses with the exception of my L2500 (Which I still have!) is USA made.
The G&L is probably the most versatile of the bunch. Active/Passive, Series/Parallel. I've not played a Tribute, but have heard positive comments for the most part.
The Proline is a good bass. Maple instead of Bubinga, so a bit lighter in wieght and brighter in tone. A good bass, but that era was known for their Baseball bat necks, which I like. I traded mine off for a 5-String bass.
The Pro-M is a pretty unique beast. What looks like a Humbucker, or a MusicMan pickup is actually 2 seperate Jazz pickups Siamesed together! Each pickup has a seperate 2-band preamp. The body on this one would be Flamed maple, and the neck most likely a nice thin Wenge example. I had a Fortress Masterman, which has the same electronics as the Pro-M. But for whatever reason I didn't "Bond" with the Streamer like I did with the Fortress. But it was a Very GOod, and Fairly Rare bass!
I'd personally go Pro-M, L2500, ProLine. But I'd want to play whatever I went with first...
Feel free to PM me if you have any further curiosity of my opinions...
