Ok, this thread was opened to be able to speak about the differences between both games. Like positive things and negative things! Of course always compared with each other. Maybe one day we have some sort of collaboration and can make a fusion of some kind between both....who knows!
TS = TurboSliders
NSGP = NewstarGP
My point of view by random order:
- Skidmarks -> TS has them and it transmits a feeling of reality. Also it helps me a lot to learn with the mistakes cause i see clearly where i went out of track on previous lap!

- Chat --> TS has it much much better then NSGP. You can also change all parameters of race right there. Even though i find it a bit more hard to handle cause its not predefined menus like on NSGP for colisions ON or COM players,.... on TS you have to write commands!
- Spectator view --> Again TS has it and NSGP not!
You also can join races to drive while they are still ON but you can join only as spectator as well and follow any drivers race of your choice - Netcode --> Im not an expert on it but....it looks TS has it more smooth. On NSGP car always looks a bit blurry to me, like if its going to disappear soon. Also theres always loads of lag on NSGP and TS doesnt look like so much.
- Website --> NSGP has it much more simple and defined i think while on TS everything looks very disorganised and chaotic. Too much unclear info on the website! Its a mess of information. On NSGP, cortesy of Przemator!
Everything packed on a clear website http://www.NSGP.tk 
- Strategy --> NSGP has a clear advantage on this point. Having 3 kinds of tires and dynamic weather, Fuel, makes it unbelievably fun and unpredictable sometimes.
- Draft & Kers --> NSGP has it and TS not. Draft i think works pretty well on NSGP, KERS i cant say it really does cause it motivates cutting on turns. Also that you can repair a mistake done very easily.
- Damage --> I cant really say about this topic so well on TS but on NSGP doesnt work good at all!!!!

- NSGP costs 4€ Turbosliders costs 15€!!!
(something to be reviewed!!?) - NSGP has built in screenshot key, TS not. You haver to make printscreen + paint + paste + save....
- Synchronisation! TS has it, NSGP dont!

- Replay. Horrible system on TS where you cant advance laps and it only moves forward. Alos changing players its not done by order. Jumps from player to player but not in order of position
