Not sure??!!
First of all, I hate, hate, hate using a MOUSE when I can use a track ball and joystick and do all I want without having to open up the keyboard on my dedicated arcade.
But anyway here it goes..and it is impossible for me to rank 10 because I don't need that many reasons. Its kind of like having dual joysticks. Robotron and Smash TV and Battle Zone are all I need them for and that is good enough for me!
Spinner
TEMPEST(I would actually rank this twice if I could)
Arkanoid
Tac/Scan
Super Breakout
Tron(paired with the topfire)
Avalanche-one of my favorites..much like Kaboom! on the old Atari
Pole Position(and most any driving game)
Rollerball.
CENTIPEDE
Marble Madness
Beezer(very addictive)
Missle Command
Liberator
Crystal Castles
Golden Tee
Any shooting or flying game also benefits from this. Terminator 2 or After Burner are alot more playable.
Also Doom 3 and Return to Castle Wolfenstein are great to use in conjuction with a Top Fire with similar gameplay like Tron(cept ball instead of spinner).
Here is a pic of half of my arcade. To me, I use the controller for the game. Like Qbert config on the bottom right. Sure it is only for that and Congo, but very worth it because I love the games! A rotary on player one is another example. Not only is it a poor mans dial, but it serves it best purpose of all. IKARI WARRIORS!

Once you have it built in, you won't regret it. Incidently, I would urge you to go for a 3 inch track.
