Don't get me wrong, I agreed with your main point, but wanted to point that out. 
As far as I know they had a bit less than 20000.
Every 0-Day tracker will generally offer the same content. Although there may be some perks like packs, or in the case of TL, RevTT or IPT releases from P2P groups. I have always thought that if you have a mainstream site like the aforementioned ones, and a music tracker (What, Waffles) you should be fine.
