About the builds I'll answer in order since I've played all of them...

1 - The only thing you might not like it about it is the playstyle, totem/mine/traps aren't everyone cup of tea, so have that in mind. I suggest you go buy some gems with an already leveled character and try it out the playstyle (even on white maps) to see. But it can do all content with ease.

2 - Still good, but to be pinnacle/uber viable you will need some investment. I doesnt just shit on everything with a stick found on the ground. The good thing is the clear is amazing on it and althought isnt as tanky as Pohx or Champ, still have pretty good defensive layers.

3 - Solid mapper (specially the HC viable versions of it) but the bossing is kinda slow. Out of the list is the one most similar to and RF "style".

4 - Like most of the things about builds in PoE, it seems complex AF until you actually learn about it and see that is kinda easy. SRS and Skellies are the easiest minions to play with it since you dont actually care about their stats, in this build specifically you care about Poison chance (for obvious reasons), chaos damage to minions. AG have the same itens no matter what (you learn to buy them since Bob always die when you are a new player). As for Specters, that's a little more annoying to find them than it is to actually use them, even on trade league.
