Executor is actually quite good. It doesn't use a real MacOS, but it also doesn't require a Mac ROM image. Also, the current versino is color and stable. The only problem I had with it was its lack of sound. Plus its shareware, so you can try it for 30 days for free.
Softmac is also good but the shareware version has a memory limit that prevents it from running EVO, so I haven't tried it with that.
Basilisk requries Windows NT, so I haven't tried that, and I have not been able to get Fusion to work, so I don't know about its quality.
