In your opinion, the fastest rom?

I've flashed a 4.4.4 rom, and now after a few years I've come back to try and breath life into the tab. Right now I am on SLimSaber 4.3.1 and it seems real smooth. My net speed isn't very fast so I can't download all and try. Is CM10 faster, or stock rom, or should I stick with SlimSaber? Rom does not need to be very stable, a few fcs no problem, but I need some rom that operates quick

Thanks,
