Also after a while extra performance becomes redundant for some things, so while Winuae will be faster than other UAEs, for things using custom chipset an user wont notice it if you give a system enough raw grunt (even the heaviest of aga games/demos appear to run more or less identically on both my Windows machine running Winuae (c2d@4.1ghz) and my AROS machine using e-uae (c2d@3.86ghz using only one core).
WinUAE still has the best configurability options, features and usability. It's not just about speed.
I agree, this is beyond the point. I rarely use any apps that'd require use of UAE. All my favorite 68k apps run directly inside MorphOS with full speed and integration (faster than they would with my WinUAE and C2Q 3.6GHz)
