I have a system six and absolutely love it - great bike. Not sure I can give you advice on which to buy since the cost difference is so large and your personal finances are, well, personal
That said - if you buy a bike that you don’t like the looks of you’re probably going to regret it eventually. Maybe not this year, but eventually you’re going to wish you’d gotten something you truly loved.
In most situations I recommend saving up to buy the item you really want rather than buying what you can afford now just to have it sooner
