I like bukkit survival as I am assuming that is the one which allows plugins like setting homes and teleporting back and forth between them, etc.
The minecraft world is vast, so being able to teleport to key areas takes a lot of the tedium out of the game. The older I get the more difficult it seems to get for me to adapt to new mods and adaptations that make the original game almost unrecognizable.
You know what would be REALLY nice is a server for honest-to-goodness adults, say 40 and older only. I'm a dedicated senior citizen Minecrafter, but I don't enjoy playing with 14 year olds. It's a whole different experience with people who are actually mature. Don't get me wrong, kids playing Minecraft is great, and I play with my own grandchildren, but kids are, ... well, kids. And they don't always play well with grownups.
