This is a little more thurough than you requested, but I think it's importiant info for your overall choice.
Infernape:
It’s high speed and has high and equal attack and special attack stats. However, it has low defense, special defense, and HP. Although it can’t learn a ton of good Special Attack moves, there a few. There also are loads of physical attack options.
Attack: Earthquake, Brick Break, Iron Tail, Shadow Claw, Stone Edge, Rock Slide, Poison Jab, U-Turn, Close Combat, Flare Blitz
Special Attack: Solar Beam, Flamethrower
Typhlosion:
It’s stats favor the Special Attack stat. It also is fast, although it has low HP and Defense comparatively. Its’ moves also have a little variation, but overall the number of favorable moves is depleted.
Attack: Rock Slide, Shadow Claw, Earthquake, and Brick Break
Special Attack: Solar Beam, Flamethrower, Focus Blast, and Eruption
Overall, I'd go with Infernape because of the better move selection compared with the stats. Typhlosion's moves don't complement the stats.
