The analysis

Claude
Jiri Prochazka by KO/TKO, 70% confidence

Prochazka's significant advantages in volume (5.38 vs 3.73 SLPM), accuracy (55% vs 38%), and reach (4 inches) create a striking mismatch. His 60% takedown accuracy provides a grappling threat that Rountree (0 takedowns landed in UFC) cannot match. Both lost to Pereira by KO, but Prochazka's overall skill set and recent win over Rakic show superior recovery.

GPT
Jiri Prochazka by KO/TKO, 71% confidence

Prochazka's higher striking volume (5.38 SLPM vs 3.73), superior striking accuracy (55% vs 38%), and greater finishing instincts give him an edge in a high-paced striking battle. While both fighters are defensively vulnerable, Prochazka's reach advantage (+4 inches) and experience at a higher level suggest he is more likely to land decisive strikes. Rountree's low grappling threat and susceptibility to pressure further favor Prochazka's aggressive style.
