Assuming you mean in a regular fight:

Original Omnitrix vs. Ultimatrix? Ultimatrix

Recalibrated Omnitrix vs. Ultimatrix? Ultimatrix (I'd consider the Recalibrated Omnitrix stronger than Original Series Omnitrix)

Original Ultimatrix vs. New Ultimatrix? New Ultimatrix(has more aliens and acts more like a stabilizer so Albedo doesn't time out.)

Biomnitrix vs. Ultimatrix? Biomnitrix

Omnitrix vs. New Ultimatrix? Omnitrix

Original Omnitrix vs. Omnitrix? Omnitrix

Ultimatrix vs. Omnitrix? Omnitrix
