Both of these machines are clearly big winners. Bitchin' 80's midi-soundtracks and great gameplay.
For me, TX gets the nod. Mostly because of:
- the very original ruleset;
- 2 ramps vs 1 ramp;
- the transporter effect;
- the out of this world pop bumper sounds.
It's obviously a matter of taste, though. As others have said, both are extremely awesome pinball machines.
