What are you gonna use it for? If it's big boost drag racing then I would suggest the rotor as they thrive on massive turbos and power comes relatively easily. I wouldn't worry about all the people that say reliability is an issue, all you have to do is look after them properly. Jump on any rotor site and they'll tell you the same (Big ports also sound awesome)

However if its just a neat streeter then maybe a SR would be a bit more subdue and easier on petrol. Saying that you can still get big power out of a SR

It really comes down to you and which you like more or what you gonna use it for.

That's my 2 cents
