I think that ic2 was in tekkit for too long, with new updates coming out with exactly the same coremod of literally everybody's tekkit base: IndustrialCraft 2. And I do think redpower is amazing but I think the textures aren't too 'techy' and the whole setup of it is too fiddly for me. And I do think ee2 was the most cheaty mod I've ever played. But though ee3 has had no new features yet, there are so many behind the scenes stuff going on such as automatic emc values adding to modded items and a whole rewrite of the api and loads more. Also there is an ic2 dev build available with no bugs that I have found. Have you seen mps! You can look like iron man, superman or make your own super robotic casing. I think the new tekkit is entirely techy, and feels a lot more 'modern' than all the other ftb modpacks and all the old tekkits and technics. And I think this was a giant refresh and I think it's for the better
