I need new rotors and im debating OEM rotors or Cross slotted and drilled aftermarket rotors... Which one would u go for?? Pics of aftermarket rotors plz. 
but only IS250 rotors.

Drilling holes in the rotor reduces it's mass, which makes it worse than a blank stock rotor. It also makes for uneven heating and cooling, leading to cracking.
You can do a search if you want a lot more and longer technical explaination, but for almost every circumstance on a street driven car drilling is about the worst thing you can do to rotors.

Not really. If you're racing the car they might offer some advantage at the expense of possibly shorter service life... but for anything street driven there's really no good reason to waste money on anything but a good properly sized set of blank rotors with good pads.
I'd suggest you read the pulp friction article linked in the thread I pointed at, it's very very informative.

IMO if youre going to order new rotors, dont get blanks, what for? Id get drilled/slotted with some new pads cause braking will be increased by a lot, people are scared cause of the stories of them cracking and such, but its all about how you take care of them. Honestly, rarely anyone especially with a ISx50 tracks their car, and when you wash them just make sure to not spray water on the rotor when its hot. Those cryogenic ones look really good and the price is not bad. So Id look into those if I were you.

Heck my dads SL55 and 997 TT have drilled rotors and my dad and I have driven the hell out of both of them with much use and abuse on the brakes including a couple track days and the rotors on both cars have held up great so far. Hell he probably even washes them after he has driven the hell out them. No problems, I would say they are a little better to resisting fade which in itself makes them worth the money.

Except that drilling rotors reduces their mass.
Which makes them -worse- for stopping than solid ones.
Seriously, anyone who likes drilled rotors simply doesn't understand pretty basic physics.
OEMs that use drilled rotors are doing so because people expect the bling factor they bring... and people with german cars are used to replacing expensive parts pretty often anyway, so they won't notice then the rotors don't last as long or stop as well.
If drilling worked you'd think NASCAR or F1 would use em. They don't though.
Anyone who still thinks drilling isn't the exact worst thing to do with rotors should go read this thread:
