Not sure about TC4, but in TC3, Im positive Ill have an MFR farm up before you get golems researched. Did golems get the ability to cut down trees ?
Lumberjacks were added in TC4. However, they only chop the trees down. You still need something (Gather golems) to collect the stuff and something (Use golems) to re-plant the saplings.
In terms of balance, yes, you can do every other form of tree farm *well* before you have all of the tree farm golems researched and built, assuming you put the same time researching and doing other stuff with TC4 as you do mining and other stuff with the other tree farm mods. The only tree farm mod that would have taken longer to get to the maintenance-free state was SC2 Galgadorian, but I did those my last world. Those were neat, yes, but I wanted to try something new/different for me.
The reason I like them is they fit in my world. I'm trying to keep the visible parts of my base as low-tech as possible. I also sometimes just like watching them do their work. Tree grows, Lumberjack chops it, Gather gathers it, and Use re-plants the sapling. It's neat watching them in action.
I had never done a pure golem tree farm before and I probably won't do the same thing the next world. I'm not in a competition to make the most unique/wild/crazy power source. I do what I find interesting and that's good enough for me.
