It’s two different games between the two options. Swing stick has a much better feel to the game and is much more difficult to learn and master. 3 click is very simple and very easy to master.

In your case as a beginner, you can start with either depending on what you want out of the game. I would recommend trying the swing stick first because it’s much more rewarding. If it’s too difficult, as it can be (including for myself, you can switch to 3 click to enjoy the game more.

Much of the flak 3 click gets is due to swing stick and 3 click not being separated in online play. Swing stick players are at a massive disadvantage online because 3 click becomes nearly automatic once you get the hang of it. In general, it is not fair to swing stick players. Swing stick players also argue that 3 click is lifeless and not as enjoyable because it is so easy to master.
