Yeah, I kind of forgot to give my opinion on this. But better late than never right?
To start off, I just want to say that I know I don't have a lot of experience with either Bukkit or Tekkit (and zero experience with hack/mine). So, I have no idea which is a better fit for the server for 2 reasons.
1 - I am not familiar with Bukkit or Tekkit and don't know their capabilities/limitations.
2 - I don't know how you want your server to function or what you visioned the server to be like when you decided that you wanted to host your own server. Because my only idea of what you want to server to be like is my very limited knowledge of the server with Bukkit. And even then there is a possibility that Bukkit didn't function the way you hoped.
But I want you to know one more thing. No matter what anyone says in this thread, you are the one that is going to decide which direction the server goes, and I trust that you will choose what's best. Remember when you made that poll about which plugins we should keep? You said that you wanted to get rid of Heroes because it was too complicated. At the time, I didn't understand what you meant by that. Now, I understand where you were coming from, and I'm even a perfect example of why you thought the plugin was too complex. All I've done with Heroes is choosen my path, and leveled it up. I still don't know how to bind or use skills. The point is, from that point on, I trusted that you would always do what you think is best, and that's why I'm not going to vote for Bukkit nor Tekkit. Because I feel that my opinion isn't valid, and that yours should be the most important factor in choosing the path that the server will take.
Holy shit that's longer than it sounded in my head...
Shouts to world peace, and the shit we yearn for.
Sometimes I worry that we only hurry to earn more.
Sometimes I worry that we only hurry to hustle.
Forgetting why we love, and all this beautiful struggle.
