Which Machop to evolve? (sorry, not experienced)

1. Level 30 one is good.

2. If you do not have any better Tyranitars, do it.

You should do nothing! Go out in cloudy day and caught another better Machop or do a Machamp raid. But if you really need one Machamp I prefer for 13A Machop, just evolve do not power it up!

Machamp - Wait. You'll find a good L35 one eventually if you hit a nest on a cloudy day.

Tyranitar - Yes. If it's your best tyranitar, it needs bite. You'll get another fast TM eventually.

Machop: Evolve the higher level one if you need a Machamp now. If you can wait, wait until you catch a L35 Machop.

Is it your only Tyranitar? Is it powered up already? If either one is true, you should FTM it.
