As a vet Dropship pilot, i have to say that it all depends on your playstyle.
if you go full hit and run like i do, Incubus are bad because you have worse maneuvering, less Dps (even if it is barely noticiable now), have penalties vs Most AA weapons (Swarms n Rails) and you cant really achieve a recharge rate of 230 hp/sec while having as much hp as a Python.
If you go for a fit that has much more staying potential, Pythons suck because you can have less eHP, collision dmg is a ***** and you get knocked by almost anything while the incubus is a bit more stable can be thrown against a wall without losing 70% of its HP. Also you got perma reps.

With the right fit, the python can be even better than the Incubus in many cases (besides dogfights)

As someone who has every vehicle skill maxxed, i can tell you the python has more potential than the Incubus, because if the incubus is used as a staying platform, you will be eventually overwhelmed by swarms that you cant outrep or out run, while a hit and run python isnt normally overwhelmed by firepower because its constantly moving and when you are, you can out run the best AA weapons: the swarm.

The python fit ive always run has 3300 HP,pro turret and afterburner and rarely gets shot down if used smartly while my best incubus fit cant barely hold itself against swarm (might have smth. to do with play style)

The best buff for ADS would be done in 2 parts:
First in the Skills; Cal ADS gives more Splash, Gal ADS gives Heatsink
Second in Suits: Amarr gives bonus to Armour eHP , Cal Gives bonus to Shield regulation and Missile RoF, Minmatar gives bonus to Speed and Torque, Gallente gives bonus to reps and Hibrid RoF.
Pilot Suit Skills gives bonus to Module Cooldown
