Do you mean the 4.91 Evilnat over Rebug? I read that 4.84.2 Rebug is more stable than recent Evilnat releases (?). Also, i tried Evilnat out for a while and i have to say that even though i was comfortable with it i felt like it had a lot more features than rebug but that i will probably never use...Feel free to correct me if i am wrong
Also, any advice is appreciated
