Ok, it's only been about 10 hours since installing but I feel it's been long enough to give a complete opinion on this ROM.
Clockwork and SPRecovery are both supported. Initial boot was very short, about 3 minutes (nice bootanimation too). Apps will not restore from the market. This ROM skips that part of the setup wizard and immediately prompts to give SU permissions for titanium backup, which is preinstalled (really nice feature I thought, even though I use the Market to restore apps so this made it a hassle for me).
However, all apps have shown for me for the first time on a Froyo ROM without running some sort of Market fix.
The ROM is pretty snappy and responsive with the stock kernel and apps open seamlessly.
I tried a few kernels and Chevy's newer kernels at 1.2ghz. SS 4.6's performance is great, 150's benchmarks and 1600's in quadrant. That isn't always the barometer but in real world use it's extremely fluid, screen transitions are great, and no lag opening any apps. Just considering the 'real world' testing it's better than any other ROM I've run. I had higher quadrant scores and lower benchmarks with Succulent Desire but there were a few instances where it would 'stutter'.
SS has a built in 'tools' section in the menu. From here you can run scripts for camera shutter sound, adblock, deleting stock apps (the usual stuff) but there are also additional options for LED notifications in just about every color and the option to change colors in the status bar and notification menu. Battery percent is displayed in %10 increments. The unlocked NFL app also works with SS 4.6.
I really like the Simply Stunning theme. A mix of smoked glass with nice cyan/blue colors.
The deal breaker for me has been the battery life. It's the worst I've seen in awhile. I've lost %20 just being idle for 3 hours. Never touching it once, and this being at 250mhz LV while the screen is off.
I REALLY wanted to love this ROM and use it for a few days at least, but personally I look for battery life first and foremost with any ROM because I am not always able to find somewhere for a quick charge. SS 4.6 runs so fluid and seamlessly that it is almost worth it. 3/5
