Which is more popular?

Hello. I am thinking about making a public version of a currently white-listed server a few of my friends and I play on. The question I bring to you today is:

Which technic pack tekkit mod is most popular in the community right now?

I would like your opinion. It would be really helpful since you guys would ultimately become the players on the server.

I think that tekkit classic is more popular right now seeing the amount of things there is to do compared to the new one.
