I can understand disliking EE, but in the end, it results in items of equivalent power. I enjoy using both in combination to get some great rigs working and have fun with all of the cool things available.
Equivalent Exchange might be a little bit faster than IC/BC to get diamonds, but it ends up being a discussion of what problem you have with your economies when people get to the state where they can produce immense amounts of diamonds, regardless of if they are IC/BC or EE. I currently enjoy playing without generators, so if you want to ban both UU Matter/Industrial Diamonds and Energy Collectors, go for it!
In the end, I question: what is your server doing for fun? Is it building and working together to advance? Then go both. Is it the journey of taming the environment slowly and working toward hard to get tools? Then go IC. If you are wanting some more casual SMP with some fun tools to build? Scrap IC and go EE!
In all of these mods, you will break an economy pretty easily, but also extend the end game and make new ways to build things.
