Help with my Legs Push Pull routine

Hello to everyone, I'm 18 years old and I want to improve my self. My main objective is aesthetics, I'm following a diet and taking fish oil and creatine. I need to improve my training program (LPPRESTREPEAT):

Legs
Abductor Machine 4x12/15
Adductor Machine 4x12/15
Squat 4x6/7
Leg Press 4x8/10
Leg Extension 4x8/10
Dumbell Romanian Deadlift 4x10
Harmstring Curl 4x8/12
Calves Press 4/6x10/15

* I read Leg extensions are bad, however I'd like to do them because I feel great. Maybe It's a unnecessary volume for the quads but I like the final pump this exercise gives to me!

Push
Barbell Bench 4x6/8
Dumbell 30° Incline Press 4x6/8
Cable Crossover 4x8/12
Dumbell Press 4x6/8
Dumbell Lateral Raises 4x8/12
3x10/12 Rope Pushdown
3x10/12 Cable OverHead ExtensionS

* I'm thinking to switch from Barbell Bench Press to Dumbell Bench Press because I have left pec bigger than other (and right tricep bigger than left tricep). Can you give me some tips? It's better to switch to dumbell or machine or keep doing with Barbell?
* Another thing is that I'm thinking to do 2 push workouts, one with Bench Press and Incline Bench press (without Seated Dumbell Press) and the other with Bench press and Seated Dumbell Press. This because I read that Incline Bench (I'm doing it at 30°) already works a lot the anterior deltoid..

Pull
Deadlift 4x6/7
Lat Pulldown V Bar 4x8/10
Seated Cable Rows 4x8/12
Straight Arm Pulldown 3x10/12
Face Pulls 4x10/12
Shurgs 4x8/10
Curl 3x8/10
Hammer Curl 3x8/10
Reverse Cable Curl 3x8/10

* Is Reverse Cable Curl unnecessary?

Thanks to everyone, loving this forum for the informations I'm finding!
