Synergy is awesome. I've been running it since last night. I do miss the customization I had in CM7 with Launcher Pro, but I like what I'm seeing so far.
Honestly, I've found CM to be pretty buggy.
Last time I tried it, GPS was hosed... So I've been using Fresh since then.
The GPS issue was mainly an AOSP rom issue with the evo. It happened all across the board with all aosp roms on the evo. It was a strange issue as some solutions worked for some and not others. Off the top of my head, there were 3 different solutions for users to try.
There's no point comparing this to an aosp like cm7. The point of this rom, like cvsin mentioned above, is if you want a sense rom.

Why anyone would want a sense rom is beyond me. It's basically AOSP with htc sense overlay. MEH.
I love CM7 especially, but I can entirely understand why someone would stick with a Sense ROM.
And everything works. 4G is still really flaky with AOSP on the Evo. The GPS isn't fully fixed. No EPST commands, which are really useful to resolve the GPS issue, too. Can't update PRL/profile.
Visually, Sense looks good to a lot of people. I'm one of them, I will admit, even though I run an AOSP ROM. The Sense widgets are very good as well, although the Launcher Pro widgets have been able to replace them for me in most applications.
Basically, I have to flash back to a Sense ROM to fix some of these issues. I love CM7 especially, but I can entirely understand why someone would stick with a Sense ROM.
