I have used both... then switched switched to Leandros 1 just 2 days back. I like this rom coz its super fluid and light on the system. I have 90mb left in the system after all the apps and datas i've had in both hybrid v1.3.2 and v3 which showed only 67mb free.
But the problem i face with leandros 1 is it is not as stable as Hybrid. It has freezed 6 times within this 2 days and hangs for no reason even with the nominal use. So I thought this leandros 2 would have overcome these issues and was planning to flash it. But the only thing bugging me is the battery life. if any user can give me a accurate time it stays with moderate use it will be really helpful.
