I thought I wanted the trx6💙 But now I'm pretty sure I'm getting the trx4 instead based on side by side comparison vids I've watched. More options I think, lighter, being able to put bigger tires on is a huge plus.
I will choose trx4. The reason is that more realistic driving is possible. The driving performance is not good enough. If you want to drive better, choose trx6. Thank you~!!
